I'll add my two cents: The kernel panic you see is due to a missing kernel component in order to mount one of your filesystems. There are several things that can go wrong: for instance 1) You did not include the support for your filesystem in the kernel. 2) You have compiled the support of your filesystem as a module. In this case you should build the initrd and pass the initrd= option to yaboot (just add it in yaboot.conf and do ybin). 3) You did all the required steps I listed above, but did not include initial ramdisk support and/or cramfs support in your monolithic kernel. In this case, the kernel will not be able to read modules from the ramdisk.

I recompiled 2.6.9 with the sleep patch #7: it does the work, but I've run into some problems that seem to be common: 1) The alsa system has some glitches 2) Sleep does not if either dri or usb are used 3) Random instabilities if I put the machine to sleep frequently (say once every 10 mins). I'm sorry not being more precise, but I am under pressure at work and do not have time to trace the bug #3 with properly. Hope these glitches will be over once the patch does it into the official kernel.

Re: does sleep work with the patched 2.6.10 kernel?

I can confirm I have exactly the same problem, and that it's been there since the beginning of the hoary release schedule. I have an ibook g4 bought in July 2004 (14" G4 1.2 Mhz). I even disabled dri and usb but still always had this problem. I never submitted a bug report beccause some people said the problem was "fixed" on Ubuntu's Bugzilla. So I always blamed my lameness...

I'm totally swamped with work this week, so will be a bit passive, but it seems we identified a specific type of Ibook G4, revision 1.1. Sleep works on revision 1.2 but not on ours. This is not true. Although I have the 1.1 ibook and would be happy if there was a fix with my specific model in mind, there is one person on that string that reports having a 1.2 for which disabling DRI also fixed his waking from sleep panic (as disabling DRI fixes my 1.1 ibook). see http://ubuntuforums.org/showthread.php? s=7a758d7b16606695ec80f6412bf586ad&t=25264&page=2&pp=10 "Bug #7464 instead addresses the G4 iBooks with the radeon 9200 card. The reporter said that disabling dri worked for him, and he has a 7455 iBook. It works for me also (iBook G4 12''), and this is my /proc/cpuinfo: processor : 0 cpu : 7447A, altivec supported clock : 599MHz revision : 1.2 (pvr 8003 0102)" Well, Mauro, disabling DRI does not work for people with revision 1.1 ibooks, so this is the problem! ASAP I'll try to apply the suggested patch to 2.6.11 toghether with the ubuntu-specific patches and I will try to build a kernel .deb.
