The problem is I can't seem to reproduce by launching the programs by hand. Though, the most current program that seem to trigger this BUG is offlineimap when ran from cron. This time it was gzip, but I didn't run it by hand. My current kernel is: [dodji@tintin ~]$ uname -a Linux tintin 2.6.36-0.24.rc5.git0.fc15.i686 #1 SMP Tue Sep 21 02:35:54 UTC 2010 i686 i686 i386 GNU/Linux Please let me know if you need any further information.
I get the same oops in stock F14 Beta 2.6.35.4-28.fc14.i686.
