Contents of /var/log/messages
The log entries were line-wrapped. Here it is as an attachment.
I think I may have reproduced this in 2.6.15-1.1826.2.4_FC5. With firefox open with 27 tabs. Starting bittorrent and allowing it to ramp its speed up to 700 KB/s, eventually the system locked up, this time permanently (no log entries). The torrent I was downloading was: http://media.djangoproject.com/snakesandrubies/snakesandrubies.mp4.torrent When I didn't start firefox, bittorrent downloaded the remainder of the file (70 to 80%) without pausing. There were some silly vm snafu's in the last week or so, current builds should be ok. Can you still reproduce this ? Hit it again about 20 minutes ago with kernel-2.6.15-1.1854_FC5. I didn't hit it with FC5-t2, but adding another large file to bittorrent did me in. FC5-t2 didn't have a rapid increase in d/l rate, but I also wasn't watching this new file.

dmesg related contents after the 2 minute pause
And again in 2.6.15-1.1858_FC5 mismatch in kmem_cache_free: expected cache df7c9080, got df7c9140 df7c9140 is skbuff_head_cache. df7c9080 is skbuff_fclone_cache.
