Deja-Vu.. I'm having the same style of error messages with my CD-ROM, yet I
can't access it at all. Could this be releated to the "free free buffer",
or is this strickly IRQ weirdness on my end?...

In message log (2.0.33):
----
ide: i82371 PIIX (Triton) on PCI bus 0 function 57
ide0: BM-DMA at 0xf000-0xf007

ide1 at 0x170-0x177,0x376 on irq 15

If I try to mount the drive it brings the system down, stuck in a loop of
errors:
-----------
hdb: irq timeout: status=0x51
hdb: irq timeout: error=0x20
hdb: irq timeout: status=0x51
hdb: irq timeout: error=0x20
hdb: irq timeout: status=0x51
hdb: irq timeout: error=0x20
hdb: irq timeout: status=0x51
....<snip>
hdb: ATAPI reset complete
end_request: I/O Error, dev 3:40, sector 0
hdb: irq timeout: status=0x50
hdb: irq timeout: status=0x50
hdb: irq timeout: status=0x50
hdb: irq timeout: status=0x50
hdb: ATAPI reset complete
hdb: irq timeout: status=0x50
...<snip>
-------------

.... and over and over and over. Same style of error happens with kernels
2.0.30-33 and 2.0.85-101. Taking ANY suggestions anyone might have. :)
