I don't know if this is related but on my Sony VAIO desktop
the serial receive interrupt occassionally stops operating...
that is, I only receive characters queued up in the serial
port's hardware FIFO when I transmit something over the serial
link. I've never been able to track the problem down.
The effect is that the PPP link run over the serial port stalls,
fails, and hangs up. Once the machine gets into this state only
a reboot will fix it. It does not happen on any of my other boxes.

:Hello all,
:from time to time one of my machines loses dial-up
:connection with local ISP. It appears on non-regular
:basis, just at some moment connection "freezes",
:however carrier isn't lost, but a number of error
:messages from kernel shows up:
:
:PPP ON localhost> Apr 29 04:14:01 /xeon: sio1: 1 more

:And so on. Errors are reported by kernel, so killing
:pppd doesn't help, of course. Rebooting is the only
:way to go. Had anyone else tried to solve such a
:problem?

:P.S. COM2 was disabled in BIOS, and USR Courier ISA
:hangs on it. Modem is known to work fine.
