I've just upgraded from 2.2.2-RELEASE to 2.2.6-RELEASE, very smooth indeed, although ppp needed some farnarckling. However, it seems that the treatment of removable SCSI devices is different in 2.2.6 than it was in 2.2.2. Its an AHA-2940UW in this case, with 2 HDs and a Jaz. The AHA-2940UW config has not changed between upgrades, and has 'Send Start Unit' enabled on all devices. Before, I was able to /sbin/mount a spun-down Jaz drive, which, presumably, sent a start-unit to the drive, spun it up, and /sbin/mount continued (with a few warning messages about the media having changed). Now, I can only /sbin/mount when its still spinning, ie. just after use or just after a reboot. If I try after it has spun down I'm told '/dev/sd2a on /jaz: Device not configured'. I can manually start it up (re-insert) and /sbin/mount will mount it. A scsi -f /dev/ssc -p reveals "nothing" for that SCSI device when it is spun-down and "iomega jaz 1GB" when it is spun-up. The other workaround is to /sbin/mount at boot and leave it mounted. Its no great drama, the Jaz users now have 2 extra steps, a /sbin/umount before they are able to take the cart out, and a /sbin/mount after they put the original cart back. regards, taras ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Taras M.
