Does your PC have a PS/2 mouse port? This uses IRQ 12, which would explain
why your system hangs.
I ordered the same SCSI card for my new machine, but the PC hasn't been
delivered yet, so I could not try.
I changed the IRQ of the BT driver to 11 anyway - the machine does have
a PS/2 mouse port.
A suggestion to the core team: change the default IRQ for the BT driver
to 11. Don't use a device at IRQ 12 at all. More and more PCs come with
these SMC all in one peripheral chips on board, so they have PS/2 mice.
And it is very unlikely that someone will install an AH1540 and a BT
adaptor in the same machine, so why not configure all SCSI cards at IRQ 11?
