This happened after about 1.5 hours of uptime on 2.6.3-1.97 (UP
AthlonXP system).  Haven't seen this occur with previous FC2test kernels.
Comment 1 Arjan van de Ven 2004-02-24 06:10:01 EST
you're not using the nvidia bin only module, right ?
can we get an lsmod to reduce the number of suspects ?
(we need to get a list of candidates that can cause this corruption)

I'm not using any binary-only modules.
Comment 3 djh 2004-02-25 23:21:53 EST
I've been trying 2.6.3-1.100... So far no slab corruption errors, but
this message appeared when Mozilla crashed..

Comment 4 djh 2004-02-26 00:13:17 EST

It's still happening, but not as frequently.  This was with 2.6.3-2.1.238.

is this still happening ?
Comment 7 djh 2004-03-12 19:49:35 EST
Yep (2.6.3-2.1.240).  I'm about to try 253.
Comment 8 djh 2004-03-22 01:26:59 EST
I haven't seen it occur with 2.6.3-2.1.253 or 2.6.3-2.1.253.2.1, so
I'm closing this bug.
