OK, having complained about mysterious hangs that X was preventing me
from understanding, I now have a kernel that just dumps and have been
rewarded not once but twice with kernel crashdumps (oh, joy!). Can
someone give me a quick rundown on how to analyze a crashdump? AND:
one of them was "panic: free: unaligned addr", which I thought I saw
someone claiming to have fixed, but I've lost any message which might
have said that... does anyone recognize it? (The other crash was
simply described by crashdump as "panic: trap", not terribly informative.)
This is on an i386, in case the dump analysis methods are completely
different between architectures.
