Kernel bug??

[Robb Bossley]

I believe I may have located a kernel bug with 2.6.6, or at least a problem with a driver.  This is just a snippet of what happens when I start up the compiled kernel.  (The configuration is the same as was in 2.6.5, which works fine)

hda: _NEC NR-7700A, ATAPI CD/DVD-ROM drive
hdc: ST320014A, ATA DISK drive
hdc: IRQ probe failed (0xfffff7fa)
hdc: IRQ probe failed (0xfffff7fa)
hdc: IRQ probe failed (0xfffff7fa)
ide0 at 0x1f0-0x1f7, 0x3f6 on irq 14
ide1 at 0x170-0x177, 0x376 on irq 15
hdc: max request size: 128KiB
hdc: lost interrupt
hdc: lost interrupt
hdc: lost interrupt
hdc: lost interrupt

The messages do go on for a short while, setting up some other things in the kernel, but eventually come back to "hdc: lost interrupt", and then the whole thing just freezes - no progress.  My questions are twofold.

1. How do I troubleshoot this problem so that I can give the most information to those working on the kernel or driver for the hard drive?  I am not a programmer, though I understand a bit of code, but I would like to help them by giving as much information as possible.

2. Where would I send this information?

Thanks.
