AIC7XXX is still broken in 2.1.105.

The aic7xxx was broken after 5.0.13 (in 5.0.15 it was already broken),
after that version I get scsi timeouts during kernel boot and although it
keeps trying it goes nowhere. In 2.1.102 (which includes 5.0.13)
everything works fine (It's a very stable kernel), but with 5.0.15 and
later versions the kernel doesn't boot up. I think the problem is with the
aic7xxx driver and not any new scsi feature, because I have tried to
patch 2.1.102 up to 5.0.18 and I have the same problem. I have tried every
combo in lilo boot config (I mean, no_reset, pci_parity, etc) and it makes
no difference. I have an Adaptec 2940 UW adapter integrated in a
Supermicro P6DLS mainboard, and have compiled scsi support and the driver
into the kernel (that is not as a module), the detection routine display
the following info in 2.1.102:

in 2.1.104 and later kernels it stop after

(scsi0:0:-1:-1) Scanning channel for devices.

and start producing timeouts and resets.

Any idea? If you want more info ask for it, I will provide as much
as necessary.

Thanks in advance, and keep the great work, we are all waiting for
a really good 2.2 kernel soon (at least before 2000 :)

PS: I have always tried latest kernel but I can't test it anymore :(,
although after long use I have discover 2.1.102 to be a really stable
kernel (with uptimes of more than a week without a failure, and I
haven't tested it for longer times :)
