Hi,
when connecting an Digi Acceleport adapter to my Alpha, i get a warning in
the dmesg. minicom works (at least until you try to change communication
parameters), but when exiting, it will hang unkillable in "D" state.
Earlier kernels had serious issues with the OHCI host adapter being used
here causing oopses everywhere. There is also a different device
connected using mct_u232.c driver and it's working OK.
Thanks,
--jochen
