I get Sound: DMA (output) timed out - IRQ/DRQ config error?
On a PPro 200MHz (DELL OptiPlex Pro) with builting Soudblaster (OSS)
and massive access to SCSI disk AHA 1524 (tar xzvf of a big archive)
7: 686036 XT-PIC soundblaster
10: 614871 XT-PIC aha152x
I would be worth the effort to block interrupts within the drivers
only on an absolutely necessary way. Or is it already happening?

Sounds to me you are causing the ISA bus to smoke... An ISA bus can only
handle at most 16 MB / s but this is a pure theoretical limit, 8 MB / s is a
more sane value. And when the SCSI controller fills the buffer of the disk it
is damn good possible your ISA bus is flooded with data for about 1/8 sec..
this shouldn't happen, but iMHO you should use a PCI SCSI controller if you do
"massive access" to disks...
