Bit of an update, that system died again with the same error. I've
installed the testing kernel but now the box doesn't boot. It gets as
far as:
Mounted /proc
Mounting sysfs
Creating /dev
Starting udev
Loading scsi_mod.ko module
SCSI subsystem initialized
Loading de_mod.ko module
Loading aic7xxx.ko module
ACPI: PCI interrupt 000:00:0a:0[A]: no GSI - using IRQ 11
scsi0: Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 29160 B Ultra160 SCSI adapter>
aic 7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs.
Then just hangs there. CTRL-ALT-DEL does properly reset the system,
stopping md devices (not that there are any).
I tried booting with pci=noapic to see if that helped, same thing.
I've booted back into the old kernel for now. I'll have If it's if any
use this system is an IBM eServer 300.
Having a root around through the init nash script out of the initrd...
echo Starting udev
/sbin/udevstart
echo -n "/sbin/hotplug" > /proc/sys/kernel/hotplug
echo "Loading scsi_mod.ko module"
insmod /lib/scsi_mod.ko
echo "Loading sd_mod.ko module"
insmod /lib/sd_mod.ko
echo "Loading aic7xxx.ko module"
insmod /lib/aic7xxx.ko
echo "Loading dm-mod.ko module"
insmod /lib/dm-mod.ko
I guess init's not completing "Loading aic7xxx.ko module".
Will.
