http://bugzilla.novell.com/show_bug.cgi?id=531547 Summary: 2.6.31 kernel breaks thermal cpu monitoring -- regression from 2.6.37 (11.1) Classification: openSUSE Product: openSUSE 11.2 Version: Factory Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: clarkt@cnsp.com QAContact: qa@suse.de Found By: --- Created an attachment (id=313114) --> (http://bugzilla.novell.com/attachment.cgi?id=313114) dmesg output from 11.1 showing thermal is seen and used User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.2) Gecko/20090730 SUSE/3.5.2-1.1 Firefox/3.5.2 HP updated the bios for several dv series laptops. This enabled thermal management and other acpi fixes for linux. In the 2.6.27 kernel, cpu temp is read as a valid value. In the 11.2 kernels (30 and 31) this feature is broken. Reproducible: Always Steps to Reproduce: 1.install 11.1 on a HP laptop with the bios update for linux thermal and acpi 2.cpu temp is valid and shown. thermal events work. 3.install 11.2 MS5. 4. thermal events are not seen and acpi reports that the value in dsdt is invalid Actual Results: 11.1 -- thermal management works. 11.2 -- thermal management does not work Expected Results: with bios update, the cpu temp should be seen and thermal management should work. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have already filed a bug on launchpad https://bugs.launchpad.net/ubuntu/+source/linux/+bug/412167 This is caused by a buggy DSDT. BIOS updates didn't change mine. I have to use a custom DSDT to fix. Here is a link to the exact problem within the DSDT https://wiki.edubuntu.org/LaptopTestingTeam/HPdv5z Now, custom DSDT support is being removed in every distro, so I'm filing a bug. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What a terrific critical temperature Yep, this is a BIOS bug, but nevertheless the thermal zone shouldn't get ignored totally. I added a patch which should show up in some hours here: ftp://ftp.suse.com/pub/projects/kernel/kotd/master/x86_64 Best double check if the change is included: rpm -qp --changelog kernel-default.rpm |less Fri Feb 12 16:57:20 CET 2010 - trenn@suse.de

- patches.fixes/acpi_fix_no_critical_tp.patch: ACPI thermal: Don't invalidate thermal zone if critical trip point is bad (bnc#531547). Then install the kernel additionally (like that you can just test boot it and you can fall back to your old kernel matching the distri): rpm -ivh kernel-default.rpm kernel-base.rpm # eventually kernel-desktop, # doesn't matter Eventually edit /boot/grub/menu.lst to make sure the kernel gets booted or selected on next reboot in grub boot menu. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From opensuse-kernel@opensuse.org (yesterday): Is it a known problem that KOTD HEAD wasn't updated since 10-Feb-2010 ( version 2.6.33-2.99.14.0943949) ?

Yes. It was caused by a stale NFS handle. Michal fixed that a few hours ago, the kernels should be building now. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'll add you with Tested-by: clarkt@cnsp.com in the patch and send it together with some other stuff off the next days. IMO this issue is not worth backporting. From the thermal zone, there is only one passive (95C) trip point, no active ones, thus I expect you don't have any bad side effects but you cannot see the CPU temperature. If your fans are not strong enough, you may see thermal shutdowns instead of passive cooling at 95C. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
