Sata problems, slow booting

Question

Hi,
we gotta fujitsu-siemens desktop at work running arch and were having some problems booting the machine. The computer works fine after it has booted but booting takes a very long time. This is the error msg were getting
ata4: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata4.00: configured for UDMA/100
ata4: EH complete
ata4.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2
ata4.00: (irq_stat 0x40000001)
ata4.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x25 data 8 in
res 51/20:03:00:00:00/00:00:00:00:00/a0 Emask 0x40 (internal error)
ata4: soft resetting port
ata4: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata4.00: configured for UDMA/100
ata4: EH complete
The sata controller, output from lspci
00:12.0 SATA controller: ATI Technologies Inc SB600 Non-Raid-5 SATA
Boots fine if booted from the install-cd, so I guess were missing some kernel boot-time parameters or sumtin'.
Thanks for any help.
