Subject: Oops in 2.4.1
Date: Wed, 31 Jan 2001 04:36:18 +0900 [thread overview]
Message-ID: <20010131043618E.amatsus@jaist.ac.jp> (raw)
Hello.
When I boot my system (Vine Linux 2.1), my system crashes.
This oops is reproducable with the kernels: 2.4.0-ac11,
2.4.0-ac12 and 2.4.1(probably all >= 2.4.0-ac).
The decoded oops follows:
---------
ksymoops 2.3.7 on i586 2.4.1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.1/ (default)
-m /usr/src/linux/System.map (default)
Unable to handle kernel NULL pointer dereference at virtual address 00000008
