Precision M60 CD/DVD "hdc: lost interrupt" and hang on read

If I attempt to read an entire audio CD using the command:

    readcd dev=/dev/hdc -clone

then within less than minute, and sometimes a few seconds, the read
hangs, and the 'readcd' process cannot be interrupted or killed.  The
rest of the system continues working fine, but any process that attempts
to read /def/hdc (the CD/DVD device) hangs in similar fashion.  The
system message log reports the following errors:

    Jan 15 16:31:16 swag kernel: spurious 8259A interrupt: IRQ7.
    Jan 15 16:32:13 swag kernel: hdc: lost interrupt
    Jan 15 16:32:53 swag kernel: hdc: lost interrupt
    Jan 15 16:33:33 swag kernel: hdc: lost interrupt
    Jan 15 16:34:53 swag last message repeated 2 times

Sometimes there is more than one block of "lost interrupt" lines.

I run Debian sarge with a 2.6.10 kernel, custom built to exclude local
APIC support, include ACPI support (no APM), and suitable IDE block
devices.  My daily boot and use (ethernet, modem, graphics, power-off,
etc.) runs perfectly.  Playing an audio CD works fine (for example with
Gnome CD Player).  I have successfully burned a data CD once, to 10%
capacity (66MB ISO image).  Mounting and reading data CDs (iso9660)
works fine.

I have experimented with many combinations of APIC and ACPI boot
options, including compiling with APIC support and adding "noapic" and
"nolapic", adding "acpi=on", "acpi=noirq", "pci=noacpi", "pci=routeirq".
None of them solves the problem.  I have tried disabling DMA and even
enabling IRQ unmasking on /dev/hdc, with no luck.  I have scoured Google
and not found any other concrete suggestion that helps.  Alan Cox points
out that the "spurious 8259A interrupt: IRQ7" line is produced because
the APIC controller asserts IRQ 7 whenever it receives an interrupt but
no device appears to be generating one.  This may or may not be related
to the problem.
