[gentoo-user] hald is stuck

[Michael George]

I got home from work today to find that hald-addon-storage was stuck on
disk I/O and holding the load at 1 or higher.  I tried restarting hald
in /etc/init.d, but that just caused hald-probe-storage to stick,
driving the load to 2.

I've never had this happen before and I haven't migrated to a new kernel
or anything lately...

Is there any way to fix that other than reboot?

What state is the process in?  If it's in an "Uninterruptible sleep" (D)
mode then it won't die/continue until it gets whatever I/O it's
expecting.  If it doesn't (e.g. there's something wrong with the device
it's held on to) then you'll probably have to reboot.

Yes, it was in state D.  I could see it was hald, but I don't know what
device it was waiting on.  My 3Ware controller had no complaints, and I
don't think hald was managing my other HDD.  There had been no removable
disks in drives for days.

Very odd...

I had the same problem:

hald was sucking 99% cpu, removables devices didn't work
and launching hald from terminal with the option "--daemon=no 
--verbose=yes" i discovered it was on a infinite loop echo-ing
something about rules so I got in /etc/udev/rules.d
and found (by probing one by one) 99-libgphoto2.rules that
was HALS's murder.

I hope it's useful for you

I don't have that ruleset on my system.  I'll have to look into how to
"probe one by one" the rulesets if it should happen again.

Thank you for your reply!

Bah!  It's happened again to my system.

It was fine this morning when I left for work, but now
hald-addon-storage is stuck waiting on Disk IO (state of D).  I looked
in the log and the only thing I noticed was that the ide-cd system
received a lost interrupt and timed out errors on both devices (hda and
hdb).  All I have on there are IDE CD-ROM drives and they are both
empty...

Anyone have enough experience to hazard a guess as to whether I have a
drive going bad or if it's the controller?

Or could the timeout errors be unrelated?
