Bug#487875: /dev/rtc is busy

["Lars J. Liebschwager" <liebschwager@yahoo.de>]

Package: linux-image-2.6.24-1-amd64
Version: 2.6.24-7

For a few months there is no use of hwclock possible
on my computer because of folowing reason:

> hwclock --debug

hwclock from util-linux-ng 2.13.1.1
hwclock: Open of /dev/rtc failed, errno=16: Device or resource busy.
No usable clock interface found.
Cannot access the Hardware Clock via any known method.

But I don't know about any program using it.

orca:/proc/driver> cat rtc
rtc_time        : 20:19:44
rtc_date        : 2008-06-24
rtc_epoch       : 1900
alarm           : 00:00:00
DST_enable      : no
BCD             : yes
24hr            : yes
square_wave     : no
alarm_IRQ       : no
update_IRQ      : no
periodic_IRQ    : no
periodic_freq   : 1024
batt_status     : okay

Solution: modularizing rtc could help??
