Subject: 2.4.19-pre5 - kernel BUG at page_alloc.c
Message-ID: <20020402123348.A20799@mail.harddata.com>

This is from Alpha UP1500 (Nautilus) with a kernel based on 2.4.19-pre5
and somewhat modified in Nautilus specific parts to be bootable on that
machine at all.  I have seen similar incidents before and they seem to
be too repeateable just to chalk them to "not really stable yet" status
of the machine in question although what is in a register a4, i.e. a
string "ghijklmn", surely looks unusual.

Anyway, the box went catatonic but before doing that left in log
files a series of oopses which decoded look like that:

ksymoops 2.4.1 on alpha 2.4.19-pre5.ink.agp.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.19-pre5.ink.agp/ (default)
     -m /boot/System.map-2.4.19-pre5.ink.agp (specified)

Warning (compare_maps): ksyms_base symbol GPLONLY_vmalloc_to_page not found in System.map.  Ignoring ksyms_base entry
