aic7xxx_dev_reset

[thierry]

Hi,

I have an adaptec scsi card (2910C) on my linux box with a freshly
installed redhat 9.0 and a 2.4.18 kernel, and a scsi plextor cd
recorder,I used cdrecord to burn a cd and I got a problem.

Here is the dmesg out :

The cdrecorder was not ready for few seconds.
I never had this problem before.

What is the problem ?

Thanks a lot.
