and also the latest official Maverick doesn't really solve the issue,
still some dropouts when downloading torrents @~200kBytes/second,
usually after 200-300 MB the dropout comes. Under all other normal
circumstances not a single dropout for days..
[0.00] Linux version 2.6.35-24-generic
thanks, looks like someone had mercy with me, the latest official 10.10
kernel does the job, about the same behavior now as with the 2.6.36
kernel mentioned above, the version running now was taken from dmesg:
[0.00] Linux version 2.6.35-23-generic (bui...@roseapple) (gcc
version 4.4.5
thanks reidi, you're ahead of us, your help desk proposal to upgrade
to kernel 2.6.36 solved all the issues I had, including the audio
glitch, which came together with a video glitch when playing movies. And
with the old kernel this 4318 bug clearly got worse when having
increased CPU load of any
PS: under given evidence it would be very nice if this 2.6.36 kernel
could be taken as the kernel for the official 10.10 maverick
distribution, especially as all the 2.6.36-rc's belong to maverick
according to the mainstream kernel list..

load on my system..

I realize this is not a help forum, but I would like to let folks know
that installing kernel 2.6.36-020636-generic #201010210905 resolved this
problem for me. It also solved an audio glitch,

I confirm everything reidi has reported with this bug report. The exact
same hardware worked correctly with 10.04. The 10.10 upgrade broke the
Broadcom 4318 device exactly as reidi described.

have experienced exactly the same problem, with the same chip and the
same kubuntu version as above. Same laptop with 9.10 runs just fine.
Running with almost no load runs fine too, even for a long time. As soon
as for example ktorrent gets started, the issue occurs within a few
seconds. So seems
** Description changed:
I suspect this is a kernel regression at 2.6.35-xx. Never had a problem
with Ubuntu 10.04.

The behavior is identical using Maverick 10.10 RC.
