Im not super-inclined to spend time tracking down a problem on this machine since the removal of the quirk is The Right Thing, but it might be worth keeping an eye on.My hardware uses BIOS for reboot but BIOS section seems reserved for BIOS bugs not fixed by Linux OS.My symptoms seem to be exactly identical to the following (closedresolved) bug.
Both works as expected on previous kernel (I used 2.6.38.7-1). Linux Xxxx 2.6.39-ARCH 1 SMP PREEMPT Tue Jun 7 05:49:02 UTC 2011 i686 Intel(R) Atom(TM) CPU Z510 1.10GHz GenuineIntel GNULinux. Jun 16 21:51:32 Xxxx kernel: 0.088715 CompuLab SBC-FITPC2 series board. ![]() One of the important things is to find out if reboot really is BIOS. From my dmesg, I see the following (heavily edited for brevity). Can someone please state the additional information I need to provide, or the additional steps I need to perform to help you to investigate and fix this regression. Linux XX 2.6.39-ARCH 1 SMP PREEMPT Sat Jul 9 15:31:04 CEST 2011 i686 Intel(R) Atom(TM) CPU Z550 2.00GHz GenuineIntel GNULinux. This is on a HP nx6110 laptop and seems related to closed bug id 33302. Also know of another user with a HP nx8220 with the exact same issue. What I did not realise was that the reboot quirk prevented me from being able to try the reboot methods on the kernel parameters. The fix seems to be to remove the quirk entirely for this device. This appears to enable the default reboot method (acpi), which works fine for this device. What I dont understand is howwhy the BIOS reboot method was broken by the kernel changes. From my point of view, I dont care, since my device reboots fine with acpi. Would a kernel developer be able to commit the fix for SBC-FITPC2 i.e. So, given that at least two other users experienced problems above, it probably makes sense to fix the general issue if possible, OR modify my proposed patch to fix the other platforms that got broken at the same time as mine by those kernel changes. Then email it with a descriptionsigned off by to linux-kernelvger.kernel.org cc x86kernel.org or if you want you can just add the Signed-off-by: here and Ill take it from there for you. It seems to have been required when the default was kbd reboot, but no longer required now that default is acpi reboot. ![]() Do you think the actual linux change that broke the bios reboot method above will be investigated at all (i.e. I suppose given that my patch only addresses the device I happen to have, and not the other devices mentioned in this thread. ![]()
