linux-2.4.11-pre3-xfs oops in advansys driver

[iuchaflorin]

I am using linux-2.4.11-pre3-xfs from SGI XFS CVS on a debian woody. The
machine is a K6-III/500 with 512 MB RAM. The system is installed on two disks
attached to an advansys controller:
   scsi0 : AdvanSys SCSI 3.3G: PCI Ultra-Wide: PCIMEM 0xE080A000-0xE080A03F, IRQ 0x5
    Vendor: IBM       Model: DCHS04W           Rev: 6464
    Type:   Direct-Access                      ANSI SCSI revision: 02
    Vendor: IBM       Model: DCHS04U           Rev: 6464
    Type:   Direct-Access                      ANSI SCSI revision: 02

lspci -v shows
   00:09.0 SCSI storage controller: Advanced System Products, Inc ABP940-UW
      Flags: bus master, medium devsel, latency 64, IRQ 5
      I/O ports at d800 [size=64]
      Memory at e9000000 (32-bit, non-prefetchable) [size=256]
      Expansion ROM at <unassigned> [disabled] [size=64K]

Last night, while my wife was browsing using Netscape, the machine looked up
hard. This is what the serial console captured before oops:

advansys: adv_isr_callback: board 0: scp 0xc1840200 not on active queue

And then this oops, decoded:

ksymoops 2.4.3 on i586 2.4.11-pre3-xfs.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.11-pre3-xfs/ (default)
     -m /boot/System.map-2.4.11-pre3-xfs (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

The oops happened again:
