Bug Description
Binary package hint: linux-image
This is happening in Ubuntu 8.04 Hardy Heron. After latest kernel update, hwclock is not working anymore. Symptoms are quite similar to those reported in bug 59596. If timidity is running and you attempt to run hwclock:
hwclock --debug
hwclock from util-linux-ng 2.13.1
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.
This is happening on three machines: System76 laptop, booting linux-image-
All machines have all current updates.
Kernel version is 2.6.24-23.
hwclock works OK if you stop timidity or if you use --directisa switch.
