| |
Hi...
I have some problems with my magneto-optical drive in my linux box. When accessing the magneto-optical, i get scsi-resets every few seconds, and files written to the magneto-optical disks are corrupted.
Everything works well in 2.0.0 up to 2.0.22 and with DOS and Windoze. I notice the problems in 2.0.23 to 2.0.25.
The system is scsi-only with an adaptec AHA-2940 host adapter. The attached devices are: Fujitsu M2909 Harddisk (ID 0) Fujitsu M2511A Magnetooptical (ID 3) Toshiba XM-3701TA CD-ROM (ID 4).
There are lots of messages in the log, for example:

As I read some other mails in this list about scsi-problems, maybe this is a little bug in the kernel? Perhaps someone can help...
