The Problem:
Kernel hangs when accessing CD-R HP8100i if VIA IDE chipset support
is compiled in. If VIA IDE is not compiled in kernel, it works.
Tested kernels:
2.2.16, RedHat 7.0's 2.2.16-22, 2.2.18, 2.2.18 + Andre's IDE patch,
2.4.0. All tested kernels behave as described. Compiled using kgcc on
RedHat 7. No other problems.
Hardware:
MB Microstar K7T Pro2-A (MS-6330) - ATA 100 capable, VIA KT133.
hda: ATA-100 30GB IBM drive
hdc: CD-R HP8100i (does not support UDMA modes).
BIOS reports following status:
"hda" ATA100 mode
"hdc" PIO3 mode

I tried most of other tricks (ide1=noautotune, hdc=nodma etc. but
it did not help).
