Good! Taht narrows the field substantially. ><snip> > Having been trying to compile a new kernel today and I keep getting > various errors no matter which kernel. Just tried to compile the same > kernel still in use with same .config and get errors. Are they repeatable? That includes same "place", etc? If not, what's the nature of these? Kernel panics? Failures in compile, link? As Ken said in the other post, and I suggested in my original reply, memtest that booger. Note if failures are repeatable and how long it takes. Does it take multiple passes (indicating slow overheating) before the errors appear. > >> I still think it's hardware *unless* there have been recent changes in >> software.

Did you carefully push each memory stick, PCI card, etc. into the slots? Thermal expansion and contraction over extended periods can cause components to "walk" up out of fully seated position. Has the unit been recently moved? With todays cases, the can be a fair amount of flex that cause cards to tilt in the slot. I have one unit that I've learned to push the video card down after any handling. 'Course, I sometimes go on a tear and move a lot of things a lot. And set them on precarious perches, off level, other items on top,... well I *do* know better. > >> I wonder how long since fsck has been run.

Nothing stood > out at me. have you looked at the boot logs to see if the journaling file system (ext3) reports any oddities? Another possibility. Weak power. Even with surge suppression strips, there is a possibility some surge weakened the power supply. Or if it's old and just large enough for the load, maybe it got really warm one day and gave up some capacity. Try removing anything not essential to the task at hand (compiling kernel in this test case?), like cd reader/writers, sound cards, extra disk drives (don't really remove them, just pull the power connectors out) and see what happens. How old is the unit? Unbeknown to most, electronics used to "age" and eventually die or become extremely "flaky". I don't know if they still tend to do that (haven't had the desire to keep up) but on an older box... > >> -- >> Wit > -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
