I have changed an os from linux to freebsd 4.7-release
I installed an adaptec 29160 card as my scsi controller since freebsd
doesn't support the buslogic bt950 card. when I run my tape unit to
read or write a tape, it starts a series of events (lots of error
messages) that lead to the following:
spec_getpages:(#da/0x20000) I/O read failure (error-6) bp 0xc68321bc
After this ths system is pretty unstable. I need help decode what
this means. I assume its a hardware error. I have 3 scsi hard
drives, a western digital at scsi id 0, an quantum adn id 2, and a
seagate at id 12. These are all attached to the lvd/wide cable. I
hae a cdrom attached vi 50 pin SE on its own. my tape unit is
The systems seems very stable untill I run the tape drive.
When I attempt to reboot I get the message
syncing disks... 21 21 21 21 21 21 21....

is this indicating a failing drive 0? back scsi buffers? ???
