Subject: [Linux-ia64] Software IO-TLB Kernel panic
Date: Thu, 17 May 2001 11:44:50 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590693005601@msgid-missing> (raw)
Hi,
I am reproduceably getting kernel panics when accessing discs on an
Adaptec 39160 adapter (SCSI host 1 after the built-in QLA1280).
I am using the "new" aic7xxx driver on a 2.4.4 IA64 kernel.
I configured the kernel for DIG-compliant C0-stepping hardware.
The kernel panic occurs in map_single (arch/ia64/lib/swiotlb.c:171).
I have a 2-CPU Lion with C0-stepping CPUs. The requested
IO TLB size is 8192 when the panic occurs.
After the crash, I always have severe corruption on the filesystem that
was being accessed during the crash. e2fsck reports ~10 illegal blocks in
one inode, and many follow-up errors.
The only TLB related boot message I see is
kernel: Placing software IO TLB between 0xe000000000100000 - 0xe000000000300000
I am looking into this myself right now, but I would be grateful for hints
where to start. Any help appreciated,
Martin
