We have exactly the same situation here at it9grr.. we have to shutdown the
system every night to prenvent these problems...
Tha maxkeyup par seems to not change anything... Instead, the rxbuf and txbuf
seem to have effect on the bug... Please try to decrease these parameters (i've
no tried it, others told this to me)

The non_tx (no interrupts) problem seem to appear when there is an high
interrupt activity on the system...

Here the kernel is 2.0.33+mod14f+sccutils 2.4c...
