Summary: new kernel 2.6.19 causes aic7xxx driver to not work with
tape drive
Kernel Version: 2.6.19
Status: NEW
Severity: high

Most recent kernel where this bug did *NOT* occur: 2.6.18.4
Distribution: Debian/Stable/Sarge
Hardware Environment: dual-processor AMD opteron Software Environment: amanda 2.4.4p3-3
Problem Description:

I just tried it out and found that it caused my tape drive (Exabyte 1x10 changer with VXA-2 tape drive) to not work. The reason turned out to be the Adaptec aic7xxx driver (newer of the two) failed. Under 2.6.18.x, this newer driver works fine. Under 2.6.19 it failed. I then enabled the older (no longer supported) aic7xxx driver, disabled the newer one, and it works fine. The adapter is an Adaptec 29160N which is supposed to work fine with the newer aic7xxx driver.

Steps to reproduce:

use 2.6.19 fails with new aic7xxx driver
use 2.6.19 works with old aic7xxx driver
use 2.6.18.4 and earlier works with either driver
