next in thread | raw e-mail | index | archive | help
I am trying to run a Mylex Acceleraid 1100 in a Dell Poweredge 2450. When
running rawio against the mylex partition, the system panics within 2
minutes, always with a trap #29. I have kernel dumps for four panics, but
kgdb doesn't show any similarities between the panics (other than that they
are all #29).
This is using RELENG_4 cvsupped recently, and the APIC patch is in. I've
tried using a kernel both with and without Matt Dillon's experimental SMP
patch, but both cause problems.
If I boot this machine with kernel.GENERIC (no SMP), then rawio completes
successfully. If I run the test on a single SCSI drive not attached to the
Mylex, it completes without error regardless of whether I am using
kernel.GENERIC or my SMP-enabled kernel.
I'm wondering if anyone can help debug this problem. I can make the box
accessible on the net and give an account to anyone with sufficient
knowledge to help; I can also send the kernel dumps to anyone who is
interested.
I've looked over the CVS repository to see if there have been changes to the
driver in -CURRENT, and there do appear to be changes, but I'm not sure if
they might fix this problem. If they might, I'll install the latest current
snapshot and give it a shot, but if that avenue won't do any good I'd rather
not bother. Any info along those lines is also appreciated.
The traps almost always look like this in kgdb:
(kgdb) where
#0 boot (howto=256) at ../../kern/kern_shutdown.c:304
#1 0xc014b574 in poweroff_wait (junk=0xc0216039, howto=0)
at ../../kern/kern_shutdown.c:554
#2 0xc01e587e in trap_fatal (frame=0xff806fbc, eva=0)
at ../../i386/i386/trap.c:926
#3 0xc01e5242 in trap (frame={tf_fs = 24, tf_es = -1071448048, tf_ds = 16,
tf_edi = -1, tf_esi = 0, tf_ebp = 0, tf_isp = -8359960, tf_ebx = 0,
tf_edx = 160165, tf_ecx = 1, tf_eax = 0, tf_trapno = 29, tf_err = 0,
tf_eip = -1071757093, tf_cs = 8, tf_eflags = 582, tf_esp = 0,
tf_ss = -8359936}) at ../../i386/i386/trap.c:586
(kgdb)
Any help appreciated. Those with sufficient skill and contract hopes are
invited to contact me directly.
TIA.
