I finally managed to get some more diagnostics about my
problem here:
"boot -v" output of a RELENG_5_2 kernel from today (2004-01-31):

ata2-master: pio = 0x0c, wdma = 0x22, udma = 0x42, cable = 40 pin
(probe0: ata0:0:0:0): error 22
(probe0: ata0:0:0:0): Unretryable Error
(probe1: ata0:0:1:0): Unretryable Error
(probe1: ata0:0:1:0): Unretryable Error
[...]
(probe3: ata1:0:1:0): Retrying Command
(probe3: ata1:0:1:0): error 22
(probe3: ata1:0:1:0): Unretryable Error
[... and so on]

Removing atapci1 (the CMD 649, see below) fixes the problem
and makes the system come up without any further complaints.

I will try to test with a different controller soon and
report on the results.

Cheers,
