99% Cpu

It seems that whenever I try and connect to the net with my DWL-G122 dongle my CPU rockets to like 99%.

Ok here we go:

PID: 7405
USER: Root
PR: 25
Virt: 1620
Res: 332
SHR: 268
S
CPU: 99.8
MEM: 0.0
Time: 2.45.17 (goes high to around 3+)
Command: IP

That was the highest, everything else was ok. I don't know what to do or how ot fix it, I am running Mandriva One Live CD. In fact it happens on any live CD.

what does syslog have to say about things? can you turn on some debugging in the driver and find out where the cycles are going?

How do I turn on bedugging and where do I find the logs?

Actually, saying that, if I wanted to look at the logs I'd have to be able navigate my way to them which is not possible once the CPU load rockets.

a linux box should still be usable and responsive even at 100% cpu and a load of 1.0 (unless you're using a 10 year old machine with no memory). If not, we're probably dealing with a larger kernel bug.

logs are usually in /var/log. The command 'dmesg' is also useful, but its the kernel _ring_ buffer, which means that old messages just drop off the end of the list. Syslog is often in /var/log/syslog (it varies with different systems).

hack away. lemme know what you find.
