Rev. 3.37 sd0 : Micropolis 1 Go wd0 : Seagate 540 Mb wd1 : WD Caviar 210 Mb st0 : Tandberg TDC 3800 525 Mb DC 6525 Tape drive This configuration was smoothly working with FreeBSD 1.1.5.1 using the bt-742a-32.c driver ... >Description: FreeBSD works well with this configuration until i try to extract some data from my tape drive. After some time (during this all seems to be OK) the board seems to be locked, not responding to commands ... The kernel output is : bt0 : biodone : buffer already done (repeated 2 or 3 times) and then bt0 not responding ... I am there unable to read or write any data to the drive and i must then push the Big Red Button ... After rebooting, the file systems are broken and i loose a lot of data :-) >How-To-Repeat: try to extract the 3rd file of a tape (mt fsf 2) if the files are quite big ... it happens ! it happened to me only during a file skipping session on the tape drive, but i think a big restore or tar will reproduce it ... >Fix: ??? >Audit-Trail: >Unformatted:
