Hi,
TL;DR is that I have ported changes from the vendor driver to make this
card work.
I recently got one of those cards off ebay to try to make an LTO-4 tape
drive work (for fun). dmesg filled with debug logs and the driver
(aic79xx) had to be reloaded to make it come back. Searching for a
solution I found some comments relating to this:
- https://www.spinics.net/lists/linux-scsi/msg17274.html
- and the mail that prompted me to do this:
https://www.redhat.com/archives/fedora-kernel-list/2009-May/msg00001.html
I have prepared my changes a bit and they are currently over at github:
https://github.com/hawken93/linux/tree/fix_aic7xxx. I'm preparing to
send a patchset but I thought it would be better to start with some chat
rather than to go straight to patches :)
I currently have some problems relating to waiting for a scsi terminator
in the mail, but I have compiled a debian kernel with my patch and it
seems to work so far. I'm hoping that the scsi terminator will solve
some iuCRC errors and if it does, I think this patch tests okay from my end.
The method I have been using is that I downloaded vendor versions 2.0.15
and 2.0.26 (aic79xx versions) and had git diff them for me to look for
changes. It seems to me like the existing kernel version implements
everything in 2.0.15 so the idea of this patchset is to bring it to
2.0.26. Some changes were however left out because the kernel version
had refactored that code away.
