I'm running 2.6.28.8, so it's old. and it's not reproducible.
as can be seen below, hdc5 is my reiser4 drive. it did not
show any errors in fsck on the next boot. SMP is turned on,
but I did only use a single processor at that time. does this
problem sound familiar to anyone? is it already fixed in 2.6.30?
while compiling mozilla I got the following (and I hope the
ps ax snippet will also help):
