Memory problem in 2.4.19-pre9-ac3

Memory problem in 2.4.19-pre9-ac3

Post by Chris Ranki » Thu, 06 Jun 2002 09:10:06


I have a dual PIII box with 1.25GB of RAM (SMP kernel, devfs, CVS
ALSA, lm_sensors 2.6.3), and tonight I discovered this oops in my log:

ksymoops 2.4.5 on i686 2.4.19-pre9-ac3.  Options used

     -l /proc/modules (default)

     -m /boot/ (specified)

This oops was preceded 20 minutes earlier by this message:

Jun  4 22:49:52 twopit kernel: Trying to vfree() nonexistent vm area (f8961000)

I think that 2.4.19-pre9-ac3 still has memory problems. Still, at
least it gave me an oops. 2.4.18 spontaneously reboots itself without
warning after between 1 and 2 weeks of uptime.

1. kbuild25 version 3.0 for 2.4.19-pre9 and 2.4.19-pre9-ac3 have kbuild25 version 3.0 released yesterday.

Also I fixed some silly bugs I've left in I'm really happy that
people ARE interested in what I'm doing and provided feedback.

And filename is getting longer :)
