Hello!
I just cvsupped to 4.1-STABLE and tried to get my Compaq SMART-1 array
controller running. Unfortunalty the kernel still panics :(
First strange thing: about one or two ago i tried -CURRENT everthing was
successfully initialized and i actually could use the array. Unfortunalty
something with the vx driver was broken, so i hat to go for -STABLE again.
Second strange thing: if there are no disks attached to the board. it is
probed correctly and the kernel boots fine. If there is at least one logical
drive configured, we'll get a kernel panic. On the first look, the panic
does not exactly come from the ida code, but at least for me it looks like
the driver is doing something wrong, if there are any logical volumes
configured.
Current Hardware Configuration is:
Compaq ProSigna w/Pentium Overdrive and 88 MB Ram
2x 3Com 3C597 NICs (eisa slot 1 and 2)
1x Adaptec 1740 SCSI host adapter (eisa slot 3)
1x Adaptec 2740 SCSI host adapter (eisa slot 7)
1x Compaq SMART Array Controller (eisa slot 4)
2x Quantum Fireball 1GB (configured as mirror set)
dmesg output:
ida0: <Compaq SMART array controller> at 0x4c88-0x4c9e, irq (level)
ida0: on eisa0 slot 4
ida0: drives=1 firm_rev=2.26

Hmmm .... strange. I just tried booting the machine again while having the
ahc driver diesables (acctually set probing of the eisa busses to 6) and the
kernel boot fine, except it cannot find it's root filesystem (well, was
attached to the 2740). Therefore there must be some incompatabilty between
the ida and the ahc driver. As said above, if there are _no_ volumes
configured on the array controller, there is panic. It do not really know,
how hard it is, to resolve this isse, but it would be nice, if the compaq
eisa board would run with freebsd (at least, i would be very happy).
Unfortunalty i cannot provide a crash dump image, but if there is anything
else i can do, please let me know.
regards,
oliver
