[ cc list trimmed ] [ I guess I got unsubscribed from hackers, so I missed the front end of this. Every time I try and sort out majordomo at FreeBSD, it fails for me (like trying ask "what am I subscribed to") and all requests to postmaster seem to bitbucket. Oh well. ] This isn't good. Part of it just the chip later presenting the completion for a command that I had already timed out. But basically, we never got a response to a command, so we timed it out. Later, the chip presented us with the comamnd as being done- and being done with no errors (hence the 'context reply'). Can you say if there was a perceptible period of time between the first and second barfings? -matt > >>The bad news is that any kind of extended disk activity (e.g. kernel > >>building), results in a ton of unhealthy messages like this: > >> > >>mpt1: time out on request index = 0xe4 sequence = 0x00000cad > >>mpt1: Status 00000001; Mask 00000001; Doorbell 24000000 > >>request state On Chip > >>SCSI IO Request @ 0xff807f34 > >>Chain Offset 0x00 > >>MsgFlags 0x00 > >>MsgContext 0x000000e4 > >>Bus: 0 > >>TargetID 1 > >>SenseBufferLength 32 > >>LUN: 0x0 > >>Control 0x01000000 WRITE SIMPLEQ > >>DataLength 0x00004000 > >>SenseBufAddr 0x0005d9e0 > >>CDB[0:10] 2a 00 01 3f e1 9f 00 00 20 00 > >>SE32 0xdc3c2830: Addr=0xd0f3000 FlagsLength=0x14001000 > >>HOST_TO_IOC > >>SE32 0xdc3c2838: Addr=0xd034000 FlagsLength=0x14002000 > >>HOST_TO_IOC > >>SE32 0xdc3c2840: Addr=0xd136000 FlagsLength=0xd5001000 > >>HOST_TO_IOC LAST_ELEMENT END_OF_BUFFER END_OF_LIST > >>mpt1: mpt_done: corrupted ccb, index = 0xe4 seq = 0x00000cad request > >>state Timeout > >>mpt_request: > >>SCSI IO Request @ 0xff807e88 > >>Chain Offset 0x00 > >>MsgFlags 0x00 > >>MsgContext 0x000000e4 > >>Bus: 0 > >>TargetID 1 > >>SenseBufferLength 32 > >>LUN: 0x0 > >>Control 0x01000000 WRITE SIMPLEQ > >>DataLength 0x00004000 > >>SenseBufAddr 0x0005d9e0 > >>CDB[0:10] 2a 00 01 3f e1 9f 00 00 20 00 > >>SE32 0xdc3c2830: Addr=0xd0f3000 FlagsLength=0x14001000 > >>HOST_TO_IOC > >>SE32 0xdc3c2838: Addr=0xd034000 FlagsLength=0x14002000 > >>HOST_TO_IOC > >>SE32 0xdc3c2840: Addr=0xd136000 FlagsLength=0xd5001000 > >>HOST_TO_IOC LAST_ELEMENT END_OF_BUFFER END_OF_LIST > >>mpt_done: context reply: 0x000000e4 > >> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
