2.5.47 hangs while checking hda on PII laptop

[Eric Buddington]

This is 2.5.47, compiled for a PII laptop (Omnibook 4100) with
gcc-3.2. I fixed an earlier boot panic by disabling IDE-TCQ, but now
it hangs in the hda check (shown below) I waited at least 2 minutes
for it to unhang.

Below is as much of the boot messages as I could capture; I don't know
if the hdc error is significant (the drive had no media), but pulling
the CD-ROM did not prevent the hda hang in a subsequent boot.
