First, let me thank everyone who helped me out with getting this Jaz
drive up and running. The words of encouragement were as helpful as the
suggestions.
I'm getting some flakey results, and I was wondering if someone could
tell me where they think they're coming from. Now, whenever I try to
decompress a large file onto the Jaz drive, the file will uncompress,
than after a few seconds, my machine will hang and reboot. 8(
The latest instance that I can think of is when I was uncompressing the
netcon tarball earlier today.
I think that it may be the PAS16 SCSI interface that's causing a
bottleneck somewhere, or it may need to be tweaked. For some reason,
I'm getting parity errors and dma timeouts from nca0. I've included the
relevant dmesg output at the bottom of this message.
Any and all pointers would be greatly appreciated. Thanks in advance...
