Hello,
I performed a test on a system with several dongles, establishing
several RFCOMM links to remote devices, and transmitting data over them.
At one point, there was a kernel Oops. Please find attached the relevant
parte of the kernel log. Kernel on the box is 2.6.20-1.
Is it a known problem which can be avoided by upgrading the kernel to a
latest release?
Best Regards,
Pierre-Yves Paulus

M Paulus,
I had the same problem. Upgrade to the latest kernel and the problem
will be fixed.

Hello,
I performed a test on a system with several dongles, establishing
several RFCOMM links to remote devices, and transmitting data over them.
At one point, there was a kernel Oops. Please find attached the relevant
parte of the kernel log. Kernel on the box is 2.6.20-1.
Is it a known problem which can be avoided by upgrading the kernel to a
latest release?

Hi Richard,
Thanks a lot for the answer. I will perform the kernel update then.

Hello,
After upgrading to kernel 2.6.21-2 (in fact, the
linux-image-2.6.21-2-486_2.6.21-5_i386.deb package from debian
unstable), I performed some new tests, and it happened again.
Please find attached what I got in the logs. What's wrong here? I will
gladly perform any test or action which you may ask to help track the
problem down. Just ask.
Best Regards,
Pierre-Yves Paulus

that is not the latest upstream kernel. Try 2.6.23-rc1.

Hi Marcel,
> that is not the latest upstream kernel. Try 2.6.23-rc1.
I got a kernel panic running 2.6.23-rc6 a few minutes ago.
2 files attached:
-relevant part of /var/log/messages
-screenshot after the kernel panic
Don't know if I can supply more information about that case? Just ask.
Best Regards,
Pierre-Yves
