Can you (or better the reporter) try below? Unfortunately I don't have a
qla1280 setup here, so I couldn't test it myself.

Subject: [PATCH] qla1280: Reduce can_queue to 32
The qla1280 driver sets the scsi_host_template's can_queue field to 0xfffff
which results in an allocation failure when allocating the block layer tags
for the driver's queues like the one shown below:

In qla1280_set_defaults() the maximum queue depth is
set to 32 so adopt the scsi_host_template to it as well.

Can you (or better the reporter) try below? Unfortunately I don't have a
qla1280 setup here, so I couldn't test it myself.

Subject: [PATCH] qla1280: Reduce can_queue to 32
The qla1280 driver sets the scsi_host_template's can_queue field to 0xfffff
which results in an allocation failure when allocating the block layer tags
for the driver's queues like the one shown below:

In qla1280_set_defaults() the maximum queue depth is
set to 32 so adopt the scsi_host_template to it as well.
