Hello All,
Does anybody else have (had) trouble with SCSI timeouts
on a linux box with RTAI on it ?
This are the messages i found in /var/log/message.
they happen after doing something that needs disk io like ls df etc.
eventualy the commands return and are executed correctly, takes like a
minute or more.
