AIC7xxx problem

[Daniel Podlejski]

I have Adaptec SCSI controler, which with 2.4.20-ac2 boots ok:

====================================================================
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.8
        <Adaptec 2940 Ultra2 SCSI adapter>

Partition check:

====================================================================

but performance is poor - periodically all disk operations
stops for few seconds. I try to use newer drivers, but without
positiver results. Here is log from boot with verbose option:
