I'm seeing what may be a CAM problem with 3.0-release. I am using an Adaptec 2940UW: ahc0: <Adaptec 2940 Ultra SCSI adapter> rev 0x00 int a irq 12 on pci0.9.0 ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs And a st34371w disk: da0 at ahc0 bus 0 target 0 lun 0 da0: <SEAGATE ST34371W 0280> Fixed Direct Access SCSI2 device da0: 40.0MB/s transfers (20.0MHz, offset 8, 16bit), Tagged Queueing Enabled da0: 4148MB (8496960 512 byte sectors: 255H 63S/T 528C) It seems more or less happy until a lot of traffic is generated, at which point it hangs and logs errors (for that drive only) -- for example "du -s /mnt" will do it quite repeatably. When it hangs, it sounds as if the disk is repeatedly seeking with about a 1 second period. Here is what it logs: (da0:ahc0:0:0:0): parity error during Data-In phase. SEQADDR == 0x10f SCSIRATE == 0x88 (da0:ahc0:0:0:0): parity error during Command phase. SEQADDR == 0x153 SCSIRATE == 0x88 (da0:ahc0:0:0:0): parity error during Message-In phase. SEQADDR == 0x153 SCSIRATE == 0x88 [...] If i reboot FreeBSD-2.2.6, this does not happen at all. any ideas? eric To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
