There is more changes in 2.6.21-rc4 please try that. I am still getting reports of timeouts with that code but it does recover better. It may be the case that with hardware flow control transmits can take an indefinite period so increasing the timeout value could help. > It looks like the patch that was applied to 2.6.20.2 > is not enough.

Until, unless the problem is reproducible with my hardware there is not much that can be done. I'll add the better recovery logic to for next stable cycle, but still not clear what causes all the timeouts.
