Steps for me to reproduce (as root):
1) losetup /dev/loop0 losetup -o $((512*63)) /dev/loop0 /usr/src/emu/plex86/guest/hdd
2) mount /dev/loop0 /mnt
3) cp -R /chris/windows/* /mnt/windows
After a few minutes, the copy will stop. At this point, most new processes
seem to hang. Sometimes, you can get an executable to start working at
random, from which point forward it will work fine. Doing an ls in cp's
/proc/nnn directory will hang as well. Sometimes SAK (SysRq-K) will kill
hung processes, somtimes not. If it does, getty will run, but login won't
normaly, so you can't log back in.
After the freeze, SysRq-U and S won't work -- they never display the
per-device lines.
Step 3 doesn't have to be a simple cp. I did tar -cvvI /chris/windows/*
|tar -xvvI /mnt/windows (or similar) to check once, and the same thing
happened.
This is a single-drive system, so all the files in question are on the same
hda, a IBM IDE drive on an AMD Viper chipset.
