Hi, That's a well known problem for which you can find a solution in the archives: sleep is not supported on Core99 machines. Well, was not.
You can find experimental (although it worked very fine for me) support in BenH's latest tree (check penguinppc.org for instructions on getting the kernel). AFAIK, sleep works on Pismo (BenH and tigert reported success) and iMac (I tested that). G4s and Cube sleep doesn't work. You will need to make some changes to your pmud pwrctl file, so it might take some work. Good Luck PS: You can find hacked pwrctl files for iMac and iBook on my website at http://hadess.net/files/ppc/ PPS: Thanks a whole lot BenH, you fixed one of the biggest problem on Linux for PPC laptop users.
