However, when one tries to power off the system, the kernel hangs. I can get more specific details on which point this happens, but it is somewhere during the shutdown process. The only solution is to force a hard poweroff. 3. The exact version of the kernel is 2.6.23-1-powerpc, as found in the Debian Sid repositories. I haven't compiled any modules for it. ah, sid is known to have problems from time to time. I don't have problems sticking with 2.6.18-5, which works quite fine save for a couple of minor issues (the wireless card detects constantly signals of 100% quality, even if the reception is really much worse... Yes so be it, but for me this seems much better than the current, witch tells me its about 50% - 70%. While I know strenght IS 90% - 100%. On the other hand, the wireless resumes flawlessly from sleep, which I find more valuable than knowing exactly how bad the signal is), That WAS a treat. I wonder why they F* that up. I really liked that. but I am curious to know if these problems I find with 2.6.23 are common, or just something specific to my machine I've experienced some hard resets from time to time. Idle machine results in non working keyboard after a few hours. Suspends stops functioning from time to time. Screen dimming takes the night after a few suspends. Always fan activity from some reason. Always harddisk rotating (due to ext3 witch is new to me?) reiser shut down the disk after a fashion (started it soon after to do maintenance, but still) . In any case, I'll try 2.6.24 when it comes out. I think the developers took december off! ;D but hell yeah. .22 and .23 seems to have some irritating flaws, but the logs show squat and without a functioning keyboard its hard to see whats going on. seems that bluetooth/usb is mighty dependent on some the same hid stuff, witch leaves me quite alone with the usb mouse witch still functions(???) while a usb keyboard is as good as firewood.

Hi, As always, just my two cents of the top of my head - not really trying to provide a solution. The technically sound folks here might provide a better idea.

Ah, it's things like these that scares me from upgrading! Do let us know as and when this gets fixed. The screen is fixed to some intermediate level of brightness which I can't change. Whenever I press Fn+F1 or F2, the dialog of GTKPBButtons appears, but displaying Brightness 0%, and never changing the value nor the real brightness of the screen. I presume the Volume/mute is working fine? How about the power button? If both are yes then the issue might boil to graphics/video related packages! Does anybody else experience this?
