Hey there -- I have an "interesting" behavior with 2.6.6 and 2.6.7, and I was wondering if this list would mind helping me figure out what's causing it. Basically, the machine turns off while it's booting. It doesn't get far enough to mount any filesystems, so there aren't any logs. On a hunch, I turned on ACPI-debugging, and noticed that the kernel immediately begins spewing warnings about a critical trap (that's from memory, I can't be completely sure if that's literally the string), and that the CPU is over 120 degrees C. Now, I'm actually *underclocking* my CPU because I have very bad luck with hardware, and I happen to know that the temperature never goes above 38 degrees C (according to my BIOS and the hardware meter glued to the heat sync). 2.6.5 doesn't seem to have this problem (frequent USB-related oopses notwithstanding), and Debian's 2.6.7-1-k7 kernel package boots without issue (Debian's completely unusable module insanity notwithstanding). So, I know there is a solution to the problem somewhere, but without logs, I'm not sure how to even begin researching it. If it weren't for the fact that there are recent ACPI-enabled kernels that work fine, I'd guess that my motherboard has a broken DSTD. Did I mention I have bad luck with exploding, melting and rotting hardware? I also seem to have the ability to trigger obscure bugs in the kernel, too. Sigh. Would anyone mind orienting me and pointing me in the right direction? Thanks!
