A patch to qla1280.c.
The command sent to the card was using a 30second timeout regardless of the
timeout requested in the scsi command passed down from higher levels.
I have just been made aware of this patch by mkp - being the current owner of the driver, it would have worked a little faster if I had been CC'ed :) At first glance it looks like the patch is good, but I would like to just check it before I push it to James. Cheers, Jes The status of this problem could be changed to VERIFIED, as I see the patch is included in 2.6.19-rc1. Right? Patch is in 2.6.19. |

Create a tape with lots of data. There needs to be enough so that a rewind or a seek will take more than 30seconds. 2. Seek to end of tape. I used "mt fsf 5" (because I had 5 partitions dumped to the tape) but "mt eod" might do. Note the the tape appears to seek correctly, but the command fails. Seeking one tape file at a time ("mt fsf 1") works for me but that presumably depends on the size of the tape file. "mt rewind" from the end of the tape fails in a similar way to a long seek. Examine syslog.
