Description of problem:
Extract from /var/log/messages:
Sep 9 01:02:26 skeletor kernel: KERNEL: assertion ((int)tp->sacked_out >= 0) failed at net/ipv4/tcp_input.c (2147)
I _think_ that this was just before my compter hanged.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I didn't notice before, but I got lots of that message in /var/log/messages, and
Sep 9 02:02:49 skeletor kernel: KERNEL: assertion ((int)tp->lost_out >= 0)
failed at net/ipv4/tcp_input.c (2148)
Can these assertions be causing my copmuter lockups ?
I reverted to kernel-2.6.13-1.1535_FC5, and now I don't see any
more of the assertions, and my computer doesn't lock up.
Same thing happens with kernel-2.6.13-1.1547_FC5. It "seems" to trigger
when using BitTorrent + heavy load on the machine, not sure how deterministic
that is though.
kernel-2.6.13-1.1549_FC5 doesn't seem to have this problem. I will test it
for a another few days, and then close this bug if no one else chimes in.
this got root caused and fixed upstream.
it's very unlikely to reoccur.
