2.4.x and DAC960 issues

I have had problems using the DAC960 driver under any 2.4.x kernel
(currently using 2.4.18). I have not experienced these problems under

1. Under reasonably low loads the driver will hang. It is very
    reproducible when using the benchmark program "Bonnie." This
    problem is exacerbated when using the ext3 filing system, locking
    up almost immediately.

2. I am not sure if this is related, but I believe that it is. I see
    the message "spurious 8259A interrupt: IRQ7." Most of the
    examples of this that I have read about involve having APIC
    enabled. But, for me, this is not the case.

3. If I boot without appending the "noapic" option, the driver hangs
    after scanning the bus for cards, but before getting to
    configuring the card. This is minor. I can live with this

The machine is a Tyan S1836DLUAN-BX, dual PIII 600Mhz. The controller
is a DAC1164P w/ Firmware Version: 5.08-0-87. The problem exists with
prior versions of the firmware and either RAID 0 or RAID 5 setups.
Kernels are compiled w/ egcs-2.91.66.

Please let me know if any additional information is needed. Any help
debugging these problems would be appreciated. Thanks in advance.
