| |
My stock debian kernel (2.6.9-1-686) crashed this morning while running bittornado (btlaunchmanycurses). At that moment only one torrent was being downloaded. It looks to me like the problem is somewhere in poll() in combination with threading.
I haven't tested it using 2.6.10 as I don't even know if I can reproduce this using 2.6.9. If I do, I'll let you know.
I've included the raw oops and the output of ksymoops below. I'm not subscribed to lkml.
