I've actually been running pre-2.0.31-2 on my home machine since not
long after it came out, with few problems (the oddest thing happening
was having init die on me, but only once -- I may still have the oops in
my log files if anyone's interested). It's been stable for me, although
I have a rather lightly-loaded system. And the 2.0.30 system I maintain
for a friend has had an excellent record so far. Admittedly, it's also
not a super-loaded system, but it stays up for weeks and hasn't had to
be rebooted for crashes.
Nevertheless, I would like to see a 2.0.31 to fix the bugs that have
been reported. But I'd hope that will hold everyone until 2.2, as any
more time spent on 2.0.x is just going to take time away from
development on the 2.1.x kernels.
