same thing for me:
2.4.21-pre4-ac1 seems the most stable ever for my hardware (not a single
hang or freeze, any other kernel would freeze more or less once a day)
but still needs longer testing for validation regarding my troubles.

2.4.21-pre4-ac2 systematically hangs at shutdown/reboot ending with:
flushing ide devices: hda hdc
