test10, hangs at aic79xx probing

[maple]

Hello!

machine hangs just after

hda: 78165360 sectors (40020 MB) w/2048KiB Cache, CHS=16383/255/63,
UDMA(100)
 hda: hda1 hda2 hda3 hda4 < hda5 hda6 hda7 >

next should be

no oops, no panic

I've also experienced troubles with this scsi controller in test9,
kernel detected it normally, but
after reading from both disks simultaneously kernel printing huge amount
of debug and refused to read with io error. exact info I sent to linux-scsi,
if interested.
in test9 case, Justin Gibbs (gibbs@xxxxxxxxxxx) suggested me to try
drivers from
http://people.FreeBSD.org/~gibbs/linux/SRC/aic79xx-linux-2.6-20031106-tar.gz
and it helps. Untarring these drivers into test10 does not help, same
hang after IDE partitions probing. 2.4.22 works ok. Tell me, if you 
need more info.
