[Bug 45928] Re: High error rate on UMTS modem

[Mathias Hasselmann]

I was tracking the bug by playing with the MTU for the point-to-point
link (smaller packets -> higher probability for the packet to pass the
lossy link), by watching the output of ifconfig and by switching
kernels. Guess you have to put you hands on the source code for finding
the bug (trying kernel.org version of 2.6.15+, 2.6.8; compare them);
reported the bug here 'cause it is some kind of Ubuntu issue, but also
because I do not care enough for fixing it/reporting it upstream to the
right kernel hacker.
