Package: linux-image-2.6.30-1-powerpc
Version: 2.6.30-1
Severity: important
Tags: patch


The powerpc RTC support has changed to use RTC_DEV_GENERIC, rather than
the RTC_DEV_PPC option in 2.6.29 and below. The configuration needs to
be updated to use RTC_DEV_GENERIC, indeed, the RTC_DEV_PPC option has
been deleted in 2.6.30. The relevent patch causing the issue is here.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=bcd68a70cb0eee556d86d93133aa150319bd9f53

Steps to reproduce:

Boot using this kernel on a PPC platform. The init scripts will complain
that the RTC cannot be accessed.

Steps to fix:

Rebuild kernel with CONFIG_RTC_DEV_GENERIC=y. I've done this and it
works perfectly.

Actually, I think the scope of this bug is resolved (though it looks
like you have found a different one). The requested config option did
get added, and I verified that it does fix the issue with rtc
discovery on my system (mac mini). I just confirmed that this did not
regress in 2.6.30-3.

Would you mind filing a separate bug for this? I'd suggest using the
reportbug tool to collect more information about your system.

Also, if you could test one of the snapshot builds of 2.6.31 (see
http://wiki.debian.org/DebianKernel), that would provide useful
information.
