Here are some temperatures from my machine read from the bios on reboot. I gave it minimal activity for the minutes prior to reboot. Win98, 47C XPHome, 42C Patched Linux 2.4.24 (1000Hz), 40C Patched Linux 2.6.3-rc1-mm1, 53C OUCH! Sorry, I will have to go through my latest patch and see why the temp differs so much between 2.4 and 2.6. I currently use patched 2.4.24 with Suse 8.2 for convenience. When it stopped the lockups on 2.6 I thought the 2.6 was working the same way. Daniel - I think you patched your 2.6 too. I assume it is also hot? > Any idea?
