Hello
I'm using a Dual Pentium-133 system (Tyan Tomcat III) IDE disks and
SCSI NCR810 Card, with Toshiba CDROM.
Linux Kernel - 2.0.35 with modules support.
First questions is which driver should I use: 53c7,8xx.c or ncr53c8xx.c
?
As I checked and both are also supported in the 2.1.1XX kernels.
I used the 53c7,8xx.c
Loading and unloading it when there are no SCSI devices at all, leaves
the system in a state that any 'cat /proc/interrupts' will cause kernel
Oops message.
When used with the CDROM connected, I can access the CDROM and mount it
but unloading the modules then reloading them will fail.
Reviewing the messages, It seems that the module doesn't free the IRQ
resources.
Please also reply by e-mail (erez@newplaces.com).
If needed I'll do tests for patches / provide needed information.
Thenks a lot
