--IJpNTDwzlM2Ie8A6 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable (bcc'ed to -CURRENT) Dear folks, I got a strange problem with mpt(4) when connecting with a disk array. The disk array works well when working under 160M/s mode, and 320M/s mode for RELENG_4 and Linux 2.4.20-8(?) from a stock RedHat 9 installation. I am trying to figure out what is happening in our mpt(4) driver which has caused this. Any help is appreciated. More information upon request. The message I got from the console (hand-copyed and typed) mpt1: timeout on request index=3D0xf0 sequence=3D0x00000084 mpt1: status 00000001; mask 00000001; Doorbell 24000000 request state on chip SCSI IO Request @ 0xe4ad5c5c Chain Offset 0x00 MsgFlags 0x00 MsgContext 0x000000fe Bus: 0 TargetID: 0 SenseBufferLength: 18 LUN: 0x2 Control: 0x02000500 READ UNTAGGED DataLength 0x00000024 SenseBufAddr 0x3e64ade0 CDB[0:6] 12 40 00 00 24 00 SE32 0xe4da9030; Addr=3D0x854884 FlagLength=3D0xd1000024 LAST_ELEMENT END_OF_BUFFER END_OF_LIST Thanks in advance!
