Alpha SCSI error on 2.4.0-test11

Hi All,

Qlogic SCSI support seems broken on 2.4.0-test11 on a Miata (Digital Personal WorkStation 600au).

When starting up, we get a machine check after initialing the qlogic SCSI code.

Using the Alpha kgdb, we figured out that the code is dying in scsi_wait_request().

Here's the backtrace:

scsi_wait_req (SRpnt=0xfffffc0001f9b480, cmnd=0xfffffc890000a078,
    buffer=0x100, bufflen=2, timeout=17891584, retries=6144)
    at /usr/src/linux/include/asm/atomic.h:85

Note: On the working kernels, the two controllers are 0x800 apart, but
on the broken kernels, they are only 0x400. Could the overlap
cause problems?
