aic7xxx freezes with kernel 2.4.13

[Pim Zandbergen]

Hi,

I've got a Dell PowerEdge 1300 with dual PIII's and dual aic7xxx
controllers. One controller is onboard, the other is in a PCI slot.

The system is running Red Hat 7.1 with kernel 2.4.13.

Lately, this system is experiencing freezes that may last one or two
minutes. These usually occur during heavy Samba activity. After the
freeze, the system usually recovers, but by then, the Samba clients
have timed out their operations.

Syslog shows the freezes are related to the SCSI subsystem. I'm having
trouble interpreting this information. Is my hardware suspect or could
this be a driver bug?

Syslog entries (with aic7xxx=verbose) showing the boot process and a
system freeze can be found on

Thanks,
