SubjectRe: aic7xxx broken in 2.5.53/54 ?

Hi hav    

I have to report the same problem, tomorrow I will complete the info,
including bios version and read-only tests on a disk device

At least I can say I've saw the message

> scsi0: PCI error Interrupt at seqaddr = 0x2
> scsi0: Signaled a Target Abort
> scsi1: PCI error Interrupt at seqaddr = 0x2
> scsi1: Signaled a Target Abort

Kernel 2.4.x works fine

now some info about chipset, etc...
