I'm having exactly the same hang on my IBM T30. I just tried sos' patch
to ata-lowlevel.c but the result was no change - it still hangs after the
ata1: resetting devices..
done
message. In the recent past I was able to boot if atapicam was
not configured in the kernel, but now I can't boot regardless of
the configuration of atapicam. I have to remove the CD-RW/DVD ROM
drive from the system to boot. The drive label says it's a Panasonic
UJDA720 (probably IBM's part number).

The cry has been that when war is declared, all opposition should
therefore be hushed. A sentiment more unworthy of a free country could
hardly be propagated. If the doctrine be admitted, rulers have only to
declare war and they are screened at once from scrutiny ... In war,
then, as in peace, assert the freedom of speech and of the press.
Cling to this as the bulwark of all our rights and privileges.
