Subjectautofs oops 2.4.9-ac10-jfs, 2.4.9-ac15
This, on a Debian woody box, everything modular, autofs4 module (probably
autofs.o too), 1000MHz Athlon, (nb doesn't occur from same kernel tree on
our SMP PIII with VIA Apollo Pro133x), the following chipset:

00:00.0 Host bridge: VIA Technologies, Inc. VT8363/8365 [KT133/KM133] (rev 03)
00:01.0 PCI bridge: VIA Technologies, Inc. VT8363/8365 [KT133/KM133 AGP]
00:07.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South] (rev 40)
00:07.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06)
00:07.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 16)
00:07.3 USB Controller: VIA Technologies, Inc. UHCI USB (rev 16)
00:07.4 SMBus: VIA Technologies, Inc. VT82C686 [Apollo Super ACPI] (rev 40)
00:0d.0 Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 02)
00:0f.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 0c)
01:00.0 VGA compatible controller: nVidia Corporation NV11 (rev a1)

The oops (from my 2.4.9-ac10 tree with extra ext3 & jfs patches, both in
modules not loaded at the time):

Any more info on request, but things are rather busy. Haven't yet tried
noapic/nodma, would this info be useful?
