Ubuntu errors when downloading image to Vostro 3500

[Alan Anderson]

Running Fog 0.32 on Ubuntu 10.04.4 LTS. This installation has worked imaging other computers but having issues with the Dell Vostro 3500. When downloading the image, I get various O/S errors the most common of which is a series of:
NOHZ: local_softirq_pending 08
NOHZ: local_softirq_pending 08
NOHZ: local_softirq_pending 08

Later the laptop freezes or reboots. I once received the following error:
BUG: unable to handle kernel paging request at ffffffff
IP: [<c0205b31>] fget_light+0x31/0xd0
*pde = 01679067 *pte = 00000000
Oops: 0000 [#1] SMP
last sysfile: /sys/devices/pci0000:00/0000:00lf.2/host2/target2:0:0/2:0:0:0/mode1

I am not a Linux guy but the softirq_pending error seems to be related to the Ethernet adapter. I have tested the laptop hardware including memory and all seems in good order. The Vostro 3500 is not listed in the problematic devices area.

Any thoughts, explanatioons or suggestions would be welcome.

I am experiencing the same problem, even without using Dell Vostro clients.
Receiving the
NOHZ: local_softirq_pending 08
error repeatedly regardless of the machine type.
Our short term solution to this problem was replacing all of the gigabit switches on the network with 10/100 switching. Now everything works, but slowly. I would be interested to know why this worked.
