Comment 247 for bug 22336

I did some testing today. I tried kubuntu 32 bit 8.04 - no luck.

vmlinuz-2.6.25.5-1.1-vanilla kernel from suse 64bit worked beautifully. The system goes to 800MHz once it his 90C and stays at that speed until it cools down to 75C. The graph shows it nicely. The system did not shut down and this is very important.

So we need to narrow it down to a specific patch. That is the list of suse patches http://www.mirrorservice.org/sites/ftp.opensuse.org/pub/opensuse/update/10.3/repodata/ .
http://www.mirrorservice.org/sites/ftp.opensuse.org/pub/opensuse/update/10.3/repodata/patch-kernel-4749.xml --- looks particularly suspicious and would roughly fit the timescale. I'll try to do some more testing in the evening to narrow it down.

 critical temp shutdowns on specific ThinkPad T4x(p) and
 R40 [#333043]
