Those deadlocks are definitely Pegasos-viaide related. The MorphOS team
confirmed that they had to implement a workaround for the problem.
It is easy to reproduce. Just read files from a disk at channel 1 and
another disk (or CDROM) at channel 2 at once. The system will lock up after
a few seconds.
i've been successfully using raidframe on my pegasos across a
pair of disks on each channel. i've seen some random crashes
that might be bad ram (i need to test it in a pc) but it mostly
Unfortunately the person I talked to couldn't remember the exact solution.
But it was something like acknowledging the channel 2 interrupt also in the
register set of channel 1...
there's also the workaround the cmdide driver uses on some
systems to only access one channel at a time, but it's
got performanec issues...
