G'day Doug and aic7xxx people,
I am sorry if this has been asked before, but I couldn't find an archive of the
list, so here goes:
I am now the proud owner of a 2910C, however things aint well. My machine is:
P100 / 23M / 2x510M IDE Drives
Adaptec 2910 (rev3) BIOS 1.11
Redhat 5.2 (Bastardised to handle 2.2 kernels)
Kernel 2.2.9
aic7xxx version 5.1.17/3.2.4 (compiled into the kernel, ie not a module)
IRQ 10, SCSI Host 7, Parity OFF, on board term DISABLED (though I have tried
EVERY combination)
the drives/tape unit I am playing with having been working fine on my other
system with a 2940 for months
Problems:
a). On boot if I put the 2910C with nothing connected, then the system hangs
while it is probing for SCSI devices (This may be normal, I just don't know).
b). With a terminator (SUN SCSI-2 TERM) on either chain, with no devices, the
system starts booting into linux of the IDEs, then "scsi0: aborting command due
to timeouts" start occuring when it hits the Adaptec driver section.
c). Connecting a drive/tape unit(int/ext) doesn't help, though the drives
sometimes while splash up it has found it.
d). "stpwlev" and "override_term" tweaks didn't seem to make a difference,
though not to sure if I was aggrevating the problem.
e). "dump_card" gave some interesting (not sure what it means, but intersting
non the less) :
PCI_COMMAND 0x7
DEVCONFIG 0x100
Loading Serial EEPROM...done
BIOS disabled, IO Port 0x6000, IRQ 10
IO MEM 0xe1000000, MMAP MEM 0xc280200
EEPROM is not PRESENT
SE Low Byte term enabled
<=== I could change this with "override_term"
1 host
Downloading <SNIP> 406 instructions <SNIP>
scsi: aborting command due to timeout
scsi: <SNIP> <lots of stuff referencing 0's only (eg LUN, ...etc...)>
f). "dump_sequencer" gave some even MORE interesting stuff:
(scsi0) BRKADRINT error (0x20)
Scratch Ram/SCB Array Ram Parity Error
(scsi0) SEQADDR=0x9
<=== this was sometimes "0xa" I think
What I have tried:
Searhing News/Web servers exhaustively
Reading the "README.aic7xxx" from the Linux kernel source
Patching the Kernel
Every @#$%^& combination of:
2910C card settings (ie parity ON/OFF, ...etc...)
every combination I could think of for the "stpwlev" and "override_term"
every combination of drives/tape unit (ie changing SCSI ids & order, but
not the other jumpers on the
units)
different types of terminators (eg SUN SCSI-2, SUN SCSI-3, IBM SCSI-1,
misc SCSI-1 & SCSI-2)
hitting my head against the wall; kicking the cat; watching the cricket
What am I doing wrong, or is the CARD stuffed (the "SCB Array Ram Parity Error"
sounds nasty).
All help/suggestions greatly appreciated.
Cheers,
Simon Whiting.
