lo,
well, ive several live cd systems < 2.6.19.5i386 that oops and hang boot in
aic7xxx init,
only one booting here is knoppix 5.2,
the latest unofficial debian stable 2.6.8-12-amd64-generic, which
says ACPI: PCI interrupt :00:06.0[A] -> GSI 17 (level, low) -> IRQ 17
aic7xxx: PCI0:6:0 MEM
no fix in scsi rc fixes git, now examining code from the softlockup trace
before...

added some traces,
ok it does not return from the first pci_map_registers():
[ 42.754305] Loading iSCSI transp
[ 48.848796] Loading iSCSI transport class v2.0-724.

[ 48.872628] ahc_pci_config
[ 48.
ok, overriding the first while(ahc_is_paused) that blocked before
(i see no sense for doing this in a pci mmap test function, cause
proper resource setup is required *before* using such I/O functions,
otherwise the adapter had entered SEQ paused status)
i got the kernel to boot at least at pio
