ESXi 4.1 PSOD when performing certain Linux disk operations

Hey all,

I am running ESXi 4.1 on an Intel server and I get PSOD's whenever I perform certain disk operations. It seems to happen when I partition a disk or once in a while when writing to disk.

It happens on thin or thick provisioned disks

It ONLY happens with LSI Parallel config, not LSI SAS.

I have attached the purple screen I get. It sucks that a Linux guests disk operation can crash an entire ESXi host with 15 guests on it. The guest disk operations SHOULD be irrelevant to the host.

Any help would be appreciated.

Thanks
