Description Dimitri V.L. 2006-10-05 00:32:32 UTC

Most recent kernel where this bug did not occur: none. I tried ubuntu edgy live
cd (2.6.17-x), same problems
Distribution: Ubuntu Linux, also tried booting fedora and knoppix, to no avail
Hardware Environment: MSI-S420 notebook (MS-141214 barebone)
Software Environment: kernel
Problem Description:
Just bought this notebook, and it wont boot unless I add "acpi=off" or
"hpet=disable" to the kernel parameters. This bug might be related to Bug 6984
since that is also an MSI notebook with an ATI chipset.
When I boot with no options, there are the last kernel messages:

using HPET for base-timer
using HPET for gettimeofday
Detected 2000.186 MHz processor
Using hpet for high-res timesource. 

After that, the machine hangs (even no response to sysrq key combinations).

I tried "nohpet" instead of "hpet=disable" but that doesn't work.

If more information is needed (which it probably will be), please point me to
the right resources with information on how to obtain that information. I am not
a kernel hacker.

Steps to reproduce:

boot without "acpi=off" or "hpet=disable".

Sooooo much has changed since 2.6.15.

Can you test 2.6.18?

Comment 2 Dimitri V.L. 2006-10-05 02:33:20 UTC

I upgraded from ubuntu dapper to edgy, and I run kernel 2.6.17-10 now. The
issues persists. Is there reason to believe 2.6.18 will fix this? I ask because
installing a new kernel would be risky and takes time, so it's better to be
informed in advance.

perhaps related messages in my kernel log (while booting with hpet=disable):


[17179569.184000] ACPI: HPET (v001 MSI    OEMHPET  0x07072006 MSFT 0x00000097) @
0x77fd4230
[17179569.184000] ACPI: HPET id: 0x0 base: 0xfed00000

When booting, I can also see some messages (something like BIOS not supported),
these messages do not end up in the kernel log, and they scroll away too fast.
How can I get hold of them?

Comment 3 Dimitri V.L. 2006-10-06 06:07:46 UTC

I managed to read these messages:
PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not using MMCONFIG
PCI: Cannot allocate resource region 3 of device 0000:00:00.0

happen when I boot with hpet=disable. With anything else, I only get the third
message and the machine hangs.

Do you think it is useful to try with latest kernel 2.6.18? (ie. did anything
even remotely relevant change???)

Comment 4 Andrew Morton 2006-10-06 07:57:08 UTC

uh-oh, mmconfig stuff.  Andi, could you please take a look at this one?

Comment 5 Matthew Garrett 2006-10-09 09:02:38 UTC

Dimitry,

Ubuntu won't show most of the kernel output by default. Remove the "quiet" and
"splash" arguments from the kernel command line in grub. The MMConfig stuff is
harmless.

Comment 6 Natalie Protasevich 2007-07-07 13:28:02 UTC

Dimitry,
Were you able to get the boot trace without boot parameters as it noted in #5?
And have you done any testing with latest kernels since then?
Thanks.

Comment 7 Andi Kleen 2007-07-08 13:14:38 UTC

We recently fixed a regression that could have caused this in mainline. So please
test 2.6.22 when it comes out (any day now) or apply
