aic79xx hang at boot

I have several Tyan GX28 (B2881) motherboards, model B2881G28U4H with 2
enbedded adaptec controllers:

0000:02:0a.0 SCSI storage controller: Adaptec AIC-7902 U320 (rev 10)
        Subsystem: Adaptec: Unknown device ffff
        Flags: bus master, 66Mhz, slow devsel, latency 64, IRQ 24
        I/O ports at 9000 [disabled] [size=fc780000]
        Memory at fc89c000 (64-bit, non-prefetchable) [size=8K]
        I/O ports at 9c00 [disabled] [size=256]
        Expansion ROM at 00080000 [disabled]
        Capabilities: [dc] Power Management version 2
        Capabilities: [a0] Message Signalled Interrupts: 64bit+
Queue=0/1 Enable-
        Capabilities: [94]
0000:02:0a.1 SCSI storage controller: Adaptec AIC-7902 U320 (rev 10)
        Subsystem: Adaptec: Unknown device ffff
        Flags: bus master, 66Mhz, slow devsel, latency 64, IRQ 25
        I/O ports at 9800 [disabled] [size=fc800000]
        Memory at fc89e000 (64-bit, non-prefetchable) [size=8K]
        I/O ports at 9400 [disabled] [size=256]
        Expansion ROM at 00080000 [disabled]
        Capabilities: [dc] Power Management version 2
        Capabilities: [a0] Message Signalled Interrupts: 64bit+
Queue=0/1 Enable-
        Capabilities: [94]

I'm using Justin's drivers found at
http://people.freebsd.org/~gibbs/linux/ (ver: 2.0.12) as the ones found
on the main kernel tree are too unstable for me.

These drivers work quite well once the system is booted, but often fail
to initialize correctly at boot time: the kernel often hangs while
trying to initialize the scsi subsystem as you can see here:

http://www.carpani.net/temp/DSCN1503.JPG

On one of the boxes, in particular, the error happens 100% of the time.

Here are my questions
- has anyone seen the same errors?
- is there somewhere an updated version of these drivers?
- any ideas?

Hi Andrea,

I've seen this and I think it is fixed in our most recent version.

I've tried it this morning and it seems to work. I'll do dome stress
tests. 
Thanks.
