We should have never gotten into the function body, !list_empty(&node->prio_list) (asm instructions) test should have failed (ie RAX == RDX vs 1 missing bit). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It will take some time. I also try to do a memtest.
Thanks a lot. It looks like hot hardware to me, but I'm not sure. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

You were right. Memtest revealed a lot of errors. Thanks for the tip. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Thanks for the quick verification. Hopefully, simply blowing dust out and re-seating dimms will fix it up for you. Computers are great dirt magnets.
