Have you checked the date settings recently? So I had this problem once
on my G3 Powerbook Pismo under Ubuntu-Hoary. After this sudden
power-lost everything seemed scrambled, which made no sense to me,
because I'm using ext3 and checked the disk right afterwards, nothing wrong.
I searched for a day and then I noticed that the problem was the
automatic time server synchronization in Gnome Date&Time Preferences,
which I had activated. It set my internal clock to 1970 or something
like this. I deactivated this option and never ever had problems with
sudden shutdowns, but some of the data I produced in that time still
have invalid time-stamps, which I notice every now and then hard-disk
check .
Hope this helps,
Rainer

In case this is still an unresolved issue, I can provide what I think
may be relevant information that might help. I believe this is an
issue having to do with the power manager's interaction with Linux. I
have noticed that on two of the powerbooks (one Lombard and one
Wallstreet) I have running Ubuntu Breezy on that this sudden power
down also occurs when I run on battery power quickly and repeatably
and the battery I am using is not a very good battery. If I exchange
for a really good battery, then it doesn't happen, at least as
quickly. If I run OS X or OS 9 the issue doesn't occur, even with the
bad batteries. The really annoying thing is that it also occurs
(though much less often) when I am running of the AC supply.

Hi Everyone,
Has there been any resolution of this issue? I am having these
sudden power downs on a Lombard powerbook. It only happens when I'm
active at the computer. The power just shuts off. I'm using Breezy
with the latest updates. I'm hoping the Debian people here have
figured it out so I can fix it. Linux is supposed to be stable, and
this certainly isn't.
Thanks,
Rob
I recently dist-upgraded from Ubuntu Hoary to Ubuntu Breezy (5.10)
and then began experiencing the sudden random power losses. Since
I'm running a 1998 PowerBook G3 Series (aka "Wallstreet II" or
"PDQ") my first thoughts were aging hardware, or the nearly dead
PRAM battery. (I'd LIKE to replace it, but what an ordeal!)
Ubuntu 5.10's kernel is 2.6.12-10-powerpc.
As others in this thread have mentioned, the machine NEVER powers
itself down when idle -- it's always when it's being actively used,
like composing a gmail message. (Thank goodness Google added
autosaves!) Mine has not (yet) powered down during a CPU-intensive
activity such as a compile. I removed the PCMCIA network card and
switched power supply bricks, but it still shuts down. No relevant
messages in any log, but I keep the hard drive idle most of the time
so it may just be losing the final messages most of the time.
Pbbuttonsd reports version 0.7.1 (and I have been having some other
trouble with it) so I stopped it now to see whether the reliability
is better. I'm not running any of the other daemons mentioned in the
thread -- no pmud, no mouseemu, no powernowd.
