Hello,
I cannot mount my cdwriter, plugged on a advansys controller. It hangs
the system for a while, and then there are slowdowns periodically.
A cdrom plugged on the same controller works perfectly (with the same
CDs), and the whole scsi system runs well under windows with the same
scsi configuration.
There is no difference if the driver is loaded in the kernel or as
module. The scsi chain is out of order after mounting the device. A scan
performed with writing software did not resolve the trouble.
The whole description of the system is in the attached file. Tell me if
more information are needed.
TIA for your help.
