HP Compaq 615 laptop doesn't boot starting with kernel 2.6.3x, ssb and 43 fail unless "acpi=off"?

I'm not sure at selecting component but HP Compaq 615 laptop doesn't work with kernel 2.6.30+ and work fine with <2.6.29.
I have tested Fedora 12, Ubuntu 9.10, Mandriva 2010 on it and all of them didn't work. Someone suggested that the problem is in loading pcmcia and pcmcia_core acpi modules because in this laptop we have only Express.

Will you please attach the output of acpidump on your box?
will you please try the following boot option and see whether the box can be booted?

acpidump from 2.6.28 (Ubuntu 9.04)
I've tested on Fedora 12 LiveCD:
a. idle=poll Result: doesn't boot
b. processor.max_cstate=1 Result: doesn't boot
c. nolapic Result: doesn't boot
d. acpi=off Result: works fine!
doesn't boot means that it tries to start udev but it failed (not OK nor FAILED printed) and screen become black and cdrom stops.
I got lines were udev stops (using additional params "debug udevdebug nomodeset")
udevd-work: M ATTRS match 'idVendor' '056a'(plain)
udevd-work: forward to rule:8172
udevd-work:got 'idVendor' ((null)) from cache
(after some seconds screen turns black)
p.s also I've tested mainline kernel from Ubuntu PPA (2.6.32-rc8) - doesn't work
I'm another owner of a compaq 615 laptop and I'm experiencing the same trouble.
After some searches I found this thread
were a weakness on the ssb module is found.
The problem is created by the same wifi module we have on the compaq 615,
(BCM4312 14e4:4315) so I think the defect we are talking here could be
the same problem that has been identified in the link.
Any help with this bug?
so if the b43 driver is excluded from the kernel, it boots?
I was able to boot excluding the module ssb, and I had acpi working;
probably you can have the same effect removing the module b43.
Unlikely the laptop was very noisy so I gave it back,
I can't tell you more about this fault.
I have the same trouble with the HP Compaq 615 using 2.6.33-rc2-git5 even when excluding the ssb and b43 module from the initrd. And "acpi=off" is for me a no-go kernel option since it fixes the problem by adding other problems, e.g. no SMP, no fan control etc.
Using the 22.214.171.124 and excluding the ssb and b43 module from the initrd I succeeded in particular with the kernel options "acpi=strict pci=nobios".
I also own a compaq 615,and i recompiled the lastest kernel without the pcmcia modules,but no way,we have to prevent the initrd to load ssb and b43 on boot,maybe they could be loaded later in a higher runlevel,can you tell me how to exclude these mudules from the initrd??thanks..
@8disk, all those people which have trouble with the HP Compaq 615 and the developers of hp_wmi, the HP laptop WMI hotkeys driver.
Excluding ssb from the initrd seems to be a neccessary prerequisite to let the HP Compaq 615 boot with the linux kernel 2.6.3. But one should not forget to exclude hp_wmi (the HP laptop WMI hotkeys driver), too. The latter one puts the HP Compaq 615 into big trouble with all recent 2.6.33 kernels, Everybody can easily reproduce this by modprobing the hp_wmi driver after a (hopefully) successfull boot. One can exclude all baleful modules e.g. ssb, hp_wmi, wmi by blacklisting those modules e.g. in /etc/modprobe.d/blacklist.conf on a Debian system. Of course one has to update an existing initrd after the mentioned modification of your blacklist.conf. But even when doing so, boot satisfaction isn't guaranteed at any boot. Thus, there seems to be a different initialisation at different boot times. But why?
Since the hp_wmi is a driver which was born for HP Compaq laptops, all kernel developers should notice that this driver dosn't work at all with recent 2.6.33 kernels, e.g. the 2.6.33-rc3.
PS: One can find my .config and blacklist.conf above.

kernel config file
great,now i'm able to boot,i just blacklisted ssb only,not b43 and/or wmi as you have said above,to prevent it from be loaded by the initramfs,in fact now i have to modprobe it manually when starting a session,however i don't use the 2.6.33 kernel but 2.6.32,i'm attaching the congif file,it's for 32bit,and i havn't had any problem with wmi or hp_wmi..all fine
I think it would be very helpful (for the kernel and driver developers) if you would be so kind to check the configuration(s) with the most recent kernel, too.
Moreover, I'm wondering why you need to modprobe ssb manually. If you tag your wlan interface to be a hotplug interface in /etc/network/interfaces your system should automatically load the b43 and ssb module.
What happens when you load hp_wmi. Are e.g. the keys "dim up" and "dim down" working properly?
The wlan interface is not "tagged" in my /etc/network/interfaces i'm going to do that,for the wmi,i usually got no hp_wmi in the modules,but only wmi,and no problem in that side,i tried to load hp_wmi and:
andrea@ott0disk:~/qt-everywhere-opensource-src-4.6.0$ dmesg |grep WMI
[ 5.045483] ACPI: WMI: Mapper loaded
[ 3385.143538] input: HP WMI hotkeys as /devices/virtual/input/input9
[ 3385.268838] HP WMI: Unknown key pressed - 0
the firt line is of course at boot time and th "Unknown key pressed" is quite strange,i pressed no key,just the caps lock switched on(BY ITSELF!)and this is the result in the dmesg.
Hi there,i've just read a news about keeping 2.6.32 releas as a long term release,good news,but what about this bug?because my pc still freezes sometimes while loading the b43 module,no way here is needed a patch.
this seems a ssb issue to me.

What additional information do you need?
someone said that he _solved_ this problem with installation Ubuntu 9.10 __amd64__, but Ubuntu 9.10 i386 have installation problem.
I can confirm this bug, still present in 2.6.34-rc2 (amd64).
Sometimes it is booting fine, sometimes (in most cases ~70%) it doesnt.
I have the same problem here on HP Mini 5102 ... tested on several kernels (from 126.96.36.199 to 2.6.34.rc2)
if I blacklist the ssb module and use broadcom-wl module instead, wifi works ... when I call modprobe ssb, the system gets frozen.

The mystery is why for Rj "acpi=off" makes the system work.
(for iX, "acpi=off" is not an option).
what do you see with "acpi=off"?
Is it true that 2.6.29 worked and 2.6.30 was the first to fail?
Can anybody try a bisect?
I confirm,with kernels < 2.6.30 it boots up but i don't know if the wireless card works,right now i'm using a vanilla kernel compiled by me in the version 2.6.32-2 and i have to modprobe b43 at the finish of the boot process,its the only way(by the way the pc freezes sometimes),with acpi=off set in the kernel command line,of course it boots well but you will be without acpi,so no battery found ecc. the bug is still present as i see also in newer kernel release...
Same here, "acpi=off" works well, but is a unacceptable workaround IMHO.
Another working workaround is the "nolapic" parameter.
sorry for doublepost, but I think its good to mention: It worked < 2.6.30 because the wireless adapter was not supported in the b43 driver back then.
so we are sure that is a b43-ssb issue...(i'm keeping an eye on "linuxwireless.com")

I have had the same problem on a laptop hp pavilion dv6-1300sb (Intel Pentium Dual-Core T4300 2.1 GHz 4Gb ram). See bug 15665
I now have tested v2.6.35-rc3 on that machine, and at least it does not block
anymore so far at startup, but it still always does block on restart after the ssb messages.
I have an HP pavillion dv6-2044el.

I confirm that removing ssb and b43, for 99% of the cases allow the kernel to boot correctly, even if in some rare cases i still get pc paralized at boot.
Re-adding these 2 modules and adding "nolapic", in my case don't solve the issue, still 50% cases the boot hang/paralize. I will attach some more details asap.
about my post below,
i can give boot visual trace logs, copyed by hand since the boot state is paralized:

After applying this patch, loading ssb does not freeze the system anymore and b43 works here. It is also included in >=188.8.131.52
That also fixed the problem for me !
