[BUG] 2.6.24-rc5: 'sysctl table check failed' when turning on printer

[Frans Pop <elendil@planet.nl>]

This is the first time I've seen this error. Last time I used the printer 
was with 2.6.24-rc3 and that time this error did not occur.

System is Pentium D x86_64 kernel running Debian unstable.
Printer is a HP Photosmart P1100 connected via parallel port.

Not sure who should be CCed on this.

ppdev0: registered pardevice
sysctl table check failed: /dev/parport/parport0/devices/ppdev0/timeslice  
Sysctl already exists
