Hi,
The serial connection of my T61 loses characters. Specifically when doing something like:
cat somelargetextfile > /dev/ttyS0
I'm seeing the first characters of the file on the other side of the serial line and then output stops. Transmission of characters resumes when keys are pressed on the sender side or the trackpoint is moved. This seems to indicate some interrupt problems on the sender side. I'm running 2.6.27 but older 2.6. kernels show the same symptoms.
Any ideas how this can be debugged further?
Cheers,
- Udo
