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

[Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp>]

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
