2.5.49: "hdb: cannot handle device with more than 16 heads"

[Eric Buddington]

This is 2.5.49, compiled for i386 with almost all modules using
gcc-3.2.  On my PII Omnibook 4100, the messages stop after the first
hda: message (where it would normally identify the drive). The same
problem existed in 2.4.48.

When booting on my Athlon (hda:Maxtor 5T040H4, hdb: Maxtor 90840D6), I
get the following boot messages:
