Hello!

I encountered a kernel oops. When that happened, I was extracting XFree86
4.2.1 sources to a reiserfs filesystem.

ksymoops 2.4.5 on i686 2.4.20-ac2. Options used
-V (default)
-k /var/log/ksymoops/20030109113946.ksyms (specified)
-l /var/log/ksymoops/20030109113946.modules (specified)
-o /lib/modules/2.4.21-pre3-ac2/ (specified)
-m /boot/System.map-2.4.21-pre3-ac2 (specified)
