sym53c8xx driver hangs

sym53c8xx driver hangs

I have a machine with a Tekram DC-390U2W and a HP Surestore 1/9 
Autoloader (with a Ultrium-1 drive) attached .
I've tried to get it to work with FC3(2.6.10-1.766_FC3) with no luck.
I've also tested it with Knoppix-3.3(2.4.24) and it works just fine 
(output from test-dump in dump.txt and from dmesg in dmesg4.txt).

If I boot with the autoloader powered up, the sym53c8xx-driver hangs 
(dmesg messages in attched dmesg1.txt) and when it has gotten that far, 
there is noting that will help but resetting the machine.

If I boot with the autoloader powered up and power it down when the 
first "batch" of error messages have been printed it detects that and 
aborts the driver and continues (dmesg2.txt)

Also attached(dmesg3.txt) is the dmesg output with "debug=0xffff".

I've replaced all SCSI-cables and the terminator, but unfortunately this 
is the only LVD-capable controller I've got(except the internal AIC-7899 
but I have no internal-68pin<->-external-68pin converter yet so I can't 
test the autoloader on that yet) so I can't test with different controller.

I've seen that there are more people having similar problem and some 
patches have also been suggested, but I haven't tested any of them yet.

Yeah, I don't think any existing patch will help you.  Could you try

Actually I got it to work when I applied the patch frage schnell posted 
jan.20 (http://marc.theaimsgroup.com/?l=linux-scsi&m=110624183606642)

> Could you try this one?

No luck, same errors as with the standard(2.1.18m) driver, and the 
driver gets stuck

Oh.  I think I'm confused as to which version of sym2 is in which version
of Linus' tree.  The same line in my development tree reads:

        if ((goal->options & PPR_OPT_MASK) || (goal->period < 0xa)) {

Does it still work if you use that?  The problem with Frage Schnell's
patch is that it won't try to negotiate U160 speeds; it'll be capped
at U80.

Well, I guess that part of the driver is rewritten a bit, I get a 
compile error if I put that in ;)
But yes, it works if I put in:

if ((tp->tinfo.goal.options & PPR_OPT_MASK) ||
     (tp->tinfo.goal.period < 0xa)) {

Oh, er, yes, looking at the diff from 2.6.10 shows I did ...

+       struct sym_trans *goal = &tp->tinfo.goal;
+       struct sym_trans *curr = &tp->tinfo.curr;

lalalla ;-)

Excellent.  Then 2.6.11 works for Ultrium tape drives.  Yay!  Tick another
annoying bug off the list ... just the strange not-working-on-Alpha bug
to investigate, I think.
