| |
On both 2.5.60 and 2.5.61 when there is no tape loaded in my SCSI DAT tape drive, access to the drive blocks for exactly 2 minutes before timing out and giving an I/O error.
# mt stat ....... < 2 minutes later > ... /dev/tape: Input/output error
< me putting a tape in the unit>
# mt stat SCSI 2 tape drive: File number=0, block number=0, partition=0. Tape block size 0 bytes. Density code 0x25 (DDS-3). Soft error count since last status=0 General status bits on (45010000): BOT WR_PROT ONLINE IM_REP_EN
I don't remember seeing this on earlier 2.5.5[0-3] or so kernels, looks like a bug in the SCSI layer.
Output from dmesg (2.5.61):
