Make sure the kernel is compiled with: options DPT_VERIFY_HINTR options DPT_HANDLE_TIMEOUTS options "DPT_TIMEOUT_FACTOR=5" These will make sure that even if there are severe bus problems, the driver will eiher recover or say where the problem is. These options are BAD for heavy laod and intense computing. They do nothing good for perfromance either. Do NOT use, except for debugging. To see what the driver does, enable debugging options, as per sys/sys/dpt.h The kernel should always be compiled with: options DPT_MEASURE_PERFORMANCE options DPT_LOST_IRQ options DDB options KTRACE ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 770.265.7340 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
