Description of problem:
I have an old Dell Optiplex DGX 5133 twin 133 Pentium 1 Machine, which runs
RH-7.2 quite happily. Its system disk runs off an Adaptec 2940U controller.
On updating to RH-7.3, the smp kernel has problems with the aic7xxx driver,
reporting errors such as:
scsi0:0:0:0: Command already completed
aic7xxx_abort returns 0x2002
scsi: device set offline - device not ready or command retry failed after bus reset
The kernel eventually panics when it can't find any scsi disks.
It works OK with the uni-processor kernel.
The problem is identical with kernel 2.4.18-3 and 2.4.18-4.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot with smp kernel
Actual Results: Kernel panics
Expected Results: Kernel should have booted!
Any developement in this?
wow, I have the same exact problem. i have a dell poweredge 7400 with dual
1.8gb processors. the install went beautifully. when i boot into smp kernel,
it hangs loading the aic7xxx module. 2.4.18-3 and 2.4.18-4 have identical
if i boot into a non smp kernel (2.4.18-3/-4) everything works perfectly.
I've been seeing a similar problem. My old Dell system (PowerEdge SP166-2)
boots perfectly using the single-processor kernel, but when I try the SMP
kernel -- both 2.4.18-3 and -4 -- I get endless sym53c8xx_reset errors.
There appears to be an issue with the smp version of the aic7xxx driver included
in the 2.4.18-3 and 4 kernels. I've cc:ed Justin Gibbs, author of that driver,
so he can comment on whether or not he expects the changes that went into the
6.2.8 version of his aic7xxx driver related to module init and irq spinlocks
will solve this problem (my guess is it will).
To christopher.cook: Your problem is decidedly different than the other two
posters. The aic7xxx module is locking their systems up entirely, while yours
is continuing to operate but not getting anywhere because interrupts aren't
being routed properly. You should be able to solve your problem by booting your
computer with the option "noapic" on the command line.
