No, this problem still exists.  How can you just wave your hands and
close the report???  Do you have an Adaptec 1542B?  Does yours work?

Bruce has offered a work-around (a string to pass to the Linux kernel)
but I don't think this should be considered a permanent solution.
IMO, known conflicting drivers should be separated.

> I close this bug.

IMHO, it should be reopened.  If you won't do it now, I'll do it the
next time I test the boot/root disks.

FYI and for the purpose of documenting the things I went through that may
help others...

I have a BusLogic 545C, and somewhere between 1.2.3 and 1.2.9 the changes
were made.  I looked at the 1.2.10 patch, bug couldn't find any Buslogic
modifications.  Before I made this particular upgrade jump, I was getting
the errors of the following nature:

>May 31 22:24:28 lucubrate kernel: BusLogic SCSI: buslogic_interrupt:

The first message would appear all the time, and sometimes multiple times
so klogd said "previous message twice."  Here's what Buslogic tech support
had to say about it via e-mail to techsup@buslogic.com (with a quick
response I might add):

I hope this helps someone else or may shed some light on the present
situation...

I have a 946C, but haven't had any problems with it through all of the
1.2.x and 1.3.x kernels.  All kernels were compiled by me using the
standard, Debian gcc-2.6.3 and libc-4.6.27.

I just tried to reproduce the problem with source-1.2.10-1.deb on a
machine here at school after a good night's sleep.  I can't reproduce
it.  Therefore, I will not report this as an additional bug.  Sorry
for the extra noise on the mailing list.

IMHO, we have to support ALL the hardware that the Linux kernel
supports.  I have a feeling that most (if not all) the Debian
developers share this opinion.  I'm sure they'll tell me if they
don't.  :-)  The proper question to ask is "how do we support
conflicting drivers in a relatively painless way?"

Mike,

Actually, I have a Buslogic board.  I know that in a very recent 1.2
revision, 6 I think it was or something, Buslogic patches were applied that
solved alot of my problems.  I have heard on Usenet this bad
board-identification problem before.  It's not particular to just us.

As for the fix, I don't know.  Ideally a 1.2.11 would be released, but most
of those kids (figuratively of course) are off to the races with 1.3.x.

I guess the question is how many debian people have Buslogic boards?  I DO.
I may be the only one.  I am sure (my speculation) that more people have
Adaptec than Buslogic (unfortunately, Buslogic is better quality and
suppurt, IMHO).

THIS RAISES THE ISSUE OF WHO OUR TARGET AUDIENCE IS again.  Just thought I
would mention that last part again for the hell of it.

I think I've narrowed the problem down to a kernel autoprobe conflict.
When my machine failed to boot the message was:

   BusLogic SCSI: buslogic_out: failed(4): BusLogic SCSI: buslogic_stat:
   status=39 intrflags=84

   BusLogic SCSI: buslogic_mailboxes: failed setting up mailboxes.

   aha1542_in failed(3): Unable to determine Adaptec DMA priority.
   Disabling board.

I got a copy of source-1.2.10-1.deb and tried compiling it without the
buslogic driver.  The source tree is messed up and it would not
compile.  I'll report this bug separately.  Finally, I got a fresh
copy of the 1.2.10 kernel source and copied the .config file from
source-1.2.10-1.deb.  I used all of the default options (the one's Ian
had set) except the buslogic driver option.  It compiled with no
problems.  I installed the new kernel by copying it to
/boot/vmlinuz-1.2.10 on my debian partition.  Now the debian system
boots and runs just fine.

Should we report this one to the kernel channel?  Can we make a
separate kernel package that avoids this conflict?

There doesn't appear to be anything relevant (to this problem) in the
HOWTO anymore.  I think the caveats were taken care of long ago.

I suspect a conflict with another driver that Ian M. has compiled into
the debian kernel.  Unfortunately, I don't know what drivers he
selected since he has not released the source package.

Yeah, I remember you mentioning that before on the debian mailing
list.  If I'm not mistaken, all the problems were related to the
1542c, not the 1542b.  The 1542b has always been pretty solid with
Linux.

You might want to check the SCSI howto for comments about
adaptec 1542{bc} interfaces.  There's a lot of caveats, and
a recommendation for changing the scsi driver so that it'll
only have one request outstanding (changing a #define).

I had this problem with my 1542c for kernels ranging from 0.99.14
or so up to 1.0.something -- needed a power-cycle to restore sanity.
It went away with one of the 1.x kernels, and now might be back with
the 1.2.10 kernel, from what you say.

I went round and round between Drew Eckhart (I think), who did the
scsi driver, and Adaptec on this.  No resolution.

PACKAGE: image
VERSION 1.2.10-1

I upgraded to the new kernel.  Now my machine hangs at boot.  The
kernel is screwing up my adaptec 1542b scsi interface in a big way.
Hardware reset does not even seem to fix it.  Powering down does,
though.
