On   5 Jun, this message from Benjamin Herrenschmidt echoed through
cyberspace:

Na. I run devfs on my Powerbook, and I am very happy. Never had any
problem. I am absolutely certain (even if it may not be true :-) that
using devfs saves me quite a number of HD spinups.

Mine show this:

mlan@pooh:~$ ll /dev/apm_bios  /dev/misc/apm_bios
lr-xr-xr-x    1 root     root           13 2003-05-14 22:42 /dev/apm_bios -> misc/apm_bios
crw-rw----    1 root     root      10, 134 1970-01-01 01:00 /dev/misc/apm_bios

This is with the Debian devfs package, which _may_ fix up a few things.
My devfs config says this:

mlan@pooh:/etc/devfs$ find . -type f |xargs grep apm
/conf.d/apm:REGISTER ^misc/apm_bios$   PERMISSIONS root.root 0660
/conf.d/pmud:REGISTER ^misc/apm_bios$   PERMISSIONS root.root 0660
/perms:REGISTER ^misc/apm_bios         PERMISSIONS root.root   0660

plus this one for setting up symlinks:

mlan@pooh:/etc/devfs$ head compat_symlinks
# Enable full compatibility mode for old device names. You may comment these
# out if you don't use the old device names. Make sure you know what you're
# doing!
REGISTER        .*              MKOLDCOMPAT
UNREGISTER      .*              RMOLDCOMPAT

I'm tempted to say: install Debian :-)

Hi all,
This has taken me a while to decide it was a bug and not a freak
accident. About one to two times a week I have noticed that my powerbook
will hand during the sleep process. Usually, when the sleep operation
completes, there is a quick screen power blank. Then about another 1.5
seconds of the LCD being illuminated, with what looks like some random
part of video memory being displayed, then finally the machine goes
to sleep. Occasionally I am seeing a freeze during the step where the
machine stays on for 1.5 seconds and has not quite been put to sleep. I
have been unable to diagnose this, as it happens so infrequently, but I
figured by posting I could hopefully get some more people experiencing
this as well. my specs:
	1ghz tipb, 1gig ram, radeon 9M, 2.4.20-ben8

I also do not seem to be doing any tasks at this time, just idling my
window manager.
