Description Matt Domsch 2000-06-29 19:11:55 UTC 
The aacraid driver v1.0.3, when statically linked into an SMP kernel, 
fails.
Kernel panic: CPU 0 trying to acquire lock again: lock count = 1
In interrupt handler - not syncing

When loaded as a module, it works fine.  Adaptec and Dell are 
investigating.

Subject: Adaptec aacraid 1.0.5 patch - fix for SMP kernel panic

Turns out the fix was actually quite simple. Looks like we were overriding
the top level
makefiles CFLAGS variable and picking up the UP define for spinlock_t.

Anyway, to make a long story short, the problem is solved.

Doug, I previously sent you the 1.0.4 patch, did you get it?

If so, the patches need to be applied in numerical order. So, apply the
1.0.4 patch
and then the 1.0.5 patch.

Thanks so much for you patients.

Cheers!!

Fixed in beta 5 with version 1.0.5 of the aacraid driver.
