[gentoo-user] Lock-ups using laptop-mode - PATCH

[Remy Blank]

I have been struggling for a few months with hard lock-ups when using
laptop-mode. Every 3-4 days, my laptop would freeze during the night,
with no message in the syslog, and for no apparent reason. The hard disk
activity light would always be on in the morning, which somehow made me
thing that it happened when the disk was started after an inactivity
period. Since I installed dbus and hald, the frequency increased to once
every night, which was a real pain. I don't think it has anything to do
with either dbus or hald, but they probably made the hard disk spin up
more often, therefore increasing the probability for the problem to happen.

Three days ago, I found this patch, which was accepted for 2.6.14, and
seems to work around a problem that sounds close enough:

It applies cleanly to gentoo-sources-2.6.12-r10, which is what I'm
currently using. I quickly made an ebuild for it, attached below with
the patch from the address above.

Well, I don't like to shout victory too early, but I have had no crash
for the last three days, even with dbus and hald running.

Just thought this info might be interesting.
