Thanks for the info. From the log it seems that it has the same failure with the bug9915. So it is marked as the duplicated bug of 9915. Thanks. *** This bug has been marked as a duplicate of bug 9915 *** there are some conflicts in the bug report. "version: 2.6.23, 2.6.24.3, 2.6.25rc3" means it can work in these kernel releases, but you also mentions that "Earliest failing kernel version: 2.6.25rc3" which means it can work before 2.6.25-rc3... so did this laptop work on any kernel release? If so, this is a regression and please tell us the latest kernel release that this laptop can work on. :) No, it doesn't work with any kernel. Just the messages differ. This bug is similar with the bug 9915. And it is caused by broken BIOS. Will you please try the custom DSDT? Created attachment 15082 [details] try the custom DSDT Will you please try the custom DSDT and confirm whether the system can be booted? How to use the custom DSDT can be found: http://www.lesswatts.org/projects/acpi/faq.php Thanks. Sorry for the delay. Yes, with the custom DSDT the kernel 2.6.23 boots. Will that be some kind of greylisting then? "Ignore/Patch the DSDT if this machine/this version"? As a short-time fix I came up with this patch. Created attachment 15172 [details]
patch for 2.6.23 - acpi-blacklist
I'd rather not blacklist this box to disable ACPI
until we are positive that we can't implement a workaround.
are both of these changes necessary?

Do any older kernels work, such as 2.6.21 or 2.6.22?
(In reply to comment #14) > I'd rather not blacklist this box to disable ACPI I agree. > until we are positive that we can't implement a workaround. > are both of these changes necessary? All we need is a one-line change in DSDT, and it can not be fixed in the kernel. I think the best way is to ping Panasonic and wait for a BIOS update. *** This bug has been marked as a duplicate of bug 9915 *** I quickly browsed the two bugs..., what exactly is the problem? It's the EC call? Has Intel contacts to Panasonic? If not at least the bug reporter could try to ask Panasonic to fix it (if someone could explain the problem detailed), AFAIK they care about Linux and may just fix this in a BIOS update. I wonder whether one of Alexey's EC patches for 2.6.26 could fix this? Have a new CF30F, and have attempted a number of different kernels but hangs on all of them. Following this bug, I also got a copy of the patched DSDT, and included it in new kernels. Still no luck. Also og note, I cannot get the system to boot even with acpi=off. This is strange, compared to the experiences described above. Looking at the dmidecode output from above, I appear to have exactly the same machine. I have tried kernels from OpenSuse-10.3 (2.6.22), Fedora-8 (2.6.22,4) ,9 (2.6.25), gparted-live (2.6.22?) etc. Non boot. Attached are dmesg outputs for fedora-9-preview, with/without acpi=off (original DSDT) and vanilla kernel 2.6.25 with patched DSDT, with/without acpi=off. I cannot get into the machine with linux under any circumstances. So I dont know how to provide you with any other information. John Created attachment 16130 [details]

I am having trouble attaching the vanilla (patched dsdt) with acpi=off output. It is basically the same, hanging at exactly the same point. I have had this and other problems on the CF30 (mk2) and have just received a bios update from panasonic. Its taken a month! It fixes my problem - couldnt boot off a USB device (optic or mem-stick) and also the DSDT problems discussed here and in Bug 10119. The bios version is now at V14. |
