dell-wmi: Received unknown WMI event (0x11)

[Felipe Balbi]

Hi,

I believe this is a regression as it was working on 2.6.37 but with
2.6.38-rc3 I can't burn DVDs with my latitute e6410. When I put a blank
double layer DVD on the drive I get:

[ 6025.385179] cdrom: This disc doesn't have any tracks I recognize!

and when I try to burn anything (well, a dry-run burn) I get:

$ growisofs -dvd-compat -use-the-force-luke=dao -use-the-force-luke=break:1913760 -speed=2 -Z /dev/dvd=my-backup-files.iso -dry-run
:-( /dev/dvd: CD_ROM_MEDIA_CHANGED ioctl failed: Inappropriate ioctl for device

Has anyone seen that before ? I'll try to reboot on 2.6.37 and try again
just to be sure and will report back on the differences.
