 |
|
I have some problems with pmud on my PB G4 400MHz.
When i issue the command
| Code: | | /etc/init.d/pmud start |
I just get some [ !! ] and no error messages what so ever. When I do a
| Code: | # pmud -d
pmud[9673]: pmud [treshold = 420, margin = 15] started
pmud[9673]: opening /dev/adb
pmud[9673]: opening /dev/pmu
pmud[9673]: fcntl(F_SETFL)
pmud[9673]: daemon stopped (fcntl(F_SETFL))
|
Then I tried
| Code: | # cat /dev/pmu <<< worked
# cat /dev/adb <<< doesn't work, IO error
|
any ideas ?

| This is a known kernel issue, the -r6 kernel is currently uploaded (but still masked for testing) and should solve there errors AFAIK. |

rsync -avz rsync.pengiunppc.org::linux-2.4-benh /my/src/dir
benh is the master of linux-ppc. his kernel tree is your friend.

i did exactly this and compiled the latest benh sources with all the right .config options, but the resulting kernel gave me a horribly corrupted X display. so my question is: how can i use a benh kernel, and get it to work in my gentoo system?
the ultimate problem i am trying to solve, which is the reason i want to use ben's code, is neither pmud nor pbbuttonsd will work reliably with gentoo's ppc-sources 2.4.19-r6 for me. on going into or coming out of sleep mode, either the kernel will first print a number of error messages on a text mode virtual console (accessed a bad area, signal 11, SEGV, backtrace, etc....) and the the whole machine will completely freeze (no keyboard combination has any effect but ctrl-command-power reset), or it will skip the error message but freeze none the less. even if sleep does work, it almost always corrupts my X display. Other than these sleep mode problems, the rest of my whole installation is great.
oh, by the way, i'm on Titanium PowerBook G4 550mhz.
any help? please?
thanks . . .

i use an ibook. my initial linux install was debian, and i had the exact same problems you speak of (pmud, video). benh is definitely a solution.
one thing to note, is when executing the rsync i mentioned above, your .config is overwritten. perhaps, your .config was overwritten, and you didnt compile with options you intended.
i spent a long time searching and testing with benh's kernels, and i have found what i think is my optimal .config. i have posted it at:

http://brady.mine.nu/kernel-conf

it is configured for an ibook2.
if you can't get to the file, try again at night time (US Pacific). i run this webserver out of my dorm on my laptop, and sometimes i take my computer to the research lab.
hope this helps.

|

one other things concerning the video. it is absolutely critical (on an ibook2, not so sure for tibook) that you include the following in your kernel boot parameters:
append="video=aty128fb keyboard_sends_linux_keycodes=1"
the video=aty128fb is absolutely necessary to have a correct X display on ibook2's. the keycode enty is also important, but im sure you've already figured that one out 
cheers!
