diskdump and aacraid

Hi,

I am using diskdump feature of Redhat enterprise linux. The system has Adaptec AAC-RAID (Rocket) (rev 02) . 'modinfo aacraid' gives version as 1.1-5[2441]. During kernel crashes, diskdump starts to dump the memory on to the disk but however fails after sometime with another 'unable to handle null pointer dereference' error. Before starting the dump process a message like the following appears on the console

start dumping to sda5
<3>aacraid: Host adapter reset request. SCSI hang ?

Wanted to check if a message like above can cause the adapter to reset when the dump is still in progress ?.

Thanks,
Chandru
