sata_mv @ asus PSCH-SR/SATA doesnt work

[Pasha <opa@nsib.ru>]

I has asus PSCH-SR/SATA with aic-8110 RAID chip, detected as 11ab:5041 
(Marvell 5041) and covered by sata_mv
Linux: slackware 9.1
kernel is 2.6.15 SMP with 2.6.15-libata1.patch.bz2

lspci -vn:
02:08.0 Class 0100: 11ab:5041 (rev 03)

but at driver load system wait till 30 sec and doesnt create /dev/sda on 
modprobe sd_mod. dmesg is:

PS.

FC5 kernel (2.6.15-1.1826.2.10_FC5smp) also wait for a long.

sd_mod also slow and says

now you can do some operations like fdisk but with error=0x01 
{ AddrMarkNotFound } and 30 sec per request. :(




kernel 1.6.14.4-ck1 (sata_mv v0.12) loads fast but says

sata_mv version 0.12
ACPI: PCI Interrupt 0000:02:08.0[A] -> GSI 26 (level, low) -> IRQ 209
sata_mvPCI master won't flush

PPS. I can give ssh for debug/improve driver.
