Comment 1 Chuck Ebbert 2011-02-11 05:21:56 UTC

drivers/net/e100.c:1277:
        timer = fw->data[UCODE_SIZE * 4];

fw->data is NULL

Is this the same machine that hit the NULL dereference in the TCP code?

Comment 2 John Reiser 2011-02-11 05:41:45 UTC

No, the e100 is a 9-yr old i686 Pentium4 1.6GHz (Northwood); the tcp is a 5-yr old Athlon64 2.0GHz socket 939.  They have been reliable, but I'll run memtest86+ again.

Comment 3 John Reiser 2011-02-11 14:11:39 UTC

Memtest86+-4.10 reports no errors after 8.25 hours; 9 passes on the e100 machine, 5.7 passes on the tcp machine.

This morning the e100 oops does not reproduce.  Yesterday it happened twice.  I have seen the tcp oops only once.

At this point I'd assign low priority to both the e100 and tcp oopses.  I was going to suggest the possibility of a gcc-4.6.0 problem and/or something with xz/lzma compression, both of which are new.

Comment 4 Josh Boyer 2011-08-02 19:45:59 UTC

Is this still happening and if so, what kernel version is it happening on?

Comment 5 John Reiser 2011-08-02 20:18:02 UTC

This problem has disappeared in normal use [not installing from DVD] of 
   kernel-2.6.38.8-35.fc15.i686
   kernel-2.6.38.8-35.fc15.i686-PAE
