Hi,
Just FYI I've tried to enable ADMA again (now running 2.6.24-rc6) but
the bug is still present:
Jan 1 16:11:21 host kernel: ata7: EH in ADMA mode, notifier 0x0 notifier_error 0x0 gen_ctl 0x1501000 status 0x400 next cpb count 0x0 next cpb idx 0x0

Although this time the above happened more than 3 hours after boot
which is much better than 2.6.22 was. In the past ~4 months ADMA was
disabled and I never had any libata-related error messages.
SMART does not show anything interesting:
