I experienced the exact same thing on a IBM 335 - in my case I had
messed up with the ACPI setup. Could you paste the output from
/proc/interupts also is your kernel running with IRQ balancing ?.
Here's the /proc/interrupts dump:
CPU0 CPU1 CPU2 CPU3
0: 11524000 0 0 0 IO-APIC-edge timer
1: 8 0 0 0 IO-APIC-edge i8042
5: 0 0 0 0 IO-APIC-level acpi
14: 13 0 0 0 IO-APIC-edge ide0
16: 2 0 0 0 IO-APIC-level ibmasm0
20: 2978604 0 2338027 0 IO-APIC-level eth0
22: 1321957 0 0 0 IO-APIC-level ips
24: 581291 0 0 0 IO-APIC-level pci-umem
29: 257154 0 0 0 IO-APIC-level eth1
NMI: 0 0 0 0
LOC: 11524185 11524201 11524194 11524121
ERR: 0
MIS: 0
I'm not sure about IRQ balancing sorry. How do I tell? The entire boot
process output is here:
http://robm.fastmail.fm/kernel/t7/bootdmesg.txt
And the config is here:
http://robm.fastmail.fm/kernel/t7/config.txt
Does that help?
Our boot doesn't pass any special parameters, just choosing the deadline
elevator...
image=/boot/bzImage-2.6.12.2
label=linux-2.6.12.2
append="elevator=deadline"
read-only
root=/dev/sda2
Thanks for your help!
