Problems with CDROMVOLCTRL
Hi,
CDROMVOLCTRL does not work with my configuration in test11. The ioctl always returns an error and volume stays the same (seen with xmcd and gtcd). I tried the patch at
*.kernel.org/pub/linux/kernel/people/axboe/patches/2.4.0-test11/cd-1.bz2
This changed the error code from some bogus large positive number to -EOPNOTSUPP :) However, volume control works fine in 2.2.17, so the hardware shouldn't be the culprit.
The cdrom drive in question is an old TEAC CD-56S on an Adaptec AHA-2940 (narrow) controller.
Cheers, Roderich

There is something to be learned from a rainstorm. When meeting with
a sudden shower, you try not to get wet and run quickly along the road.
But doing such things as passing under the eaves of houses, you still
get wet. When you are resolved from the beginning, you will not be
perplexed, though you still get the same soaking.

Please send me contents of /proc/sys/dev/cdrom/info and the sr load info.
