Subject: 2.4.19-pre10 oops
Date: Mon, 1 Jul 2002 22:10:43 +0200 [thread overview]
Message-ID: <20020701221043.A429@ping.be> (raw)
I'm using 2.4.19-pre10, and got an oops. I sometimes also get a lockup, and have no idea why.
This oops happened when reading my lkml mailbox. Ksymoops output:
Warning (compare_maps): ksyms_base symbol vmalloc_to_page_R__ver_vmalloc_to_page not found in System.map. Ignoring ksyms_base entry
Unable to handle kernel NULL pointer dereference at virtual address 00000000
