Re: PROBLEM: <AACRAID SCSI RAID DRIVER> in 2.6.25.3 -- reply to yoursuggestions

Reply to your suggestions,

1. with the kernel parameters, **aacraid.expose_physicals=0, aacraid.dacmode=0**:
I tried both parameters, but failed.

2. about "[PATCH] Stop using num_physpages in aacraid":
I am not using this patch: I saw drivers/scsi/aacraid/aachba.c (kernel-2.6.25.3)

3. about other kernels
Our machine normally runs with kernel-2.6.24 and
this failure occurs only with kernel-2.6.25 and later, including 2.6.26-rc1

Sincerely,

Not a panic, merely a problem probing the physical devices. It may seem 'forever' but that is what happens when it must issue commands to every target and lun on two physical busses. You may be able to mitigate this with the kernel parameter aacraid.expose_physicals=0, or aacraid.dacmode=0

Status 8193 (0x2003) is not a known valid response code from the Firmware, it is a result of the Firmware not processing the command in the first place.

Could be a result of 'Subject: Re: [PATCH] Stop using num_physpages in aacraid '? Could you revert that one out to see? Could you instrument the return value to the new referenced function dma_get_required_mask(&dev->pdev->dev) that is incorporated in that patch?
