Hmm.  I checked while running 2.5.12 (it still hangs) and
all the Evolution-related processes were in "S" state after
the hang.

Other ideas for me to explore?

The problem with evolution seem to be a internal one
Look at http://lists.ximian.com/archives/public/evolution-hackers/2002-March/004292.html

Pleas cc: if someone solves this ;)

kernel 2.5.10 problems

[dmacbanay]

This is the first time I've posted to this forum.  Usually when I have a 
problem with a kernel other people are having the same problem and it gets 
fixed relatively quickly.  But I've been experiencing some problems that 
haven't been going away.  If more information is needed then what I have 
given here please let me know.  I am using a SOYO K7VTA-B with a VIA 82C686B 
chipset and a Duron 750mhz processor. 

1.  Cannot mount IDE-SCSI cd drive.  This problem has been mentioned 
previously by others.  Errors occur when trying to mount it. 

2.  When ACPI support is installed the kernel gives a "Keyboard not found" 
error when booting and I have to push the reset switch to reboot.  This 
problem has also been mentioned before but I don't think anyone has related 
it to the ACPI support. 

3.  Starting sometime after kernel 2.5.1 (I couldn't compile any kernels 
from then up until 2.5.5) the Evolution email program locks up whenever 
Calender, Tasks, or Contacts is selected.  I have to go to another terminal 
and kill it. 

4.  Starting with kernel 2.5.6 (kernels 2.5.5 through 2.5.6-pre3 work)  the 
KDE program krecord closes right after it starts. 

5.  With the new ALSA routines built-in is it possible to get the midi 
output port on a Soundblaster PCI 512 to work?  I haven't been able to get 
it to function yet. 

Thank you in advance for your help

Try acpi list.

Try strace to see what it does before it dies.

Interesting. last few lines of strace output may show up what's going on.
Can you do a before/after strace on a working & non-working kernel?

Here's what shows in kernel 2.5.10.  I'm using a Soundblaster PCI 512 and I

That one likely is a known bug in the ALSA OSS emulation, Takashi
recently fixed it.

Oh, and does this still apply to 2.5.10 ?
Again, last few lines from an strace to find out what its doing when it locks
up may be useful.

Here's the last lines from the strace output until had to kill it from 
another terminal.  And this occurs in any kernel from 2.5.5 through 2.5.10.  
It may have happened before that also but I wasn't able to compile any 
kernels after 2.5.1 up until 2.5.5.

I have been aware of this bug since about 2.5.5.  It is still present 
in 2.5.10.  I have been attempting to gather more useful debugging
information.  So far, I haven't come up with anything that points
clearly to the problem.

Regarding using strace to identify the bug, it should be noted
that Evolution uses multiple processes that all communicate with
the shell process (evolution).  The process that handles access
to much of Evolution's storage for the most of the Evolution
components is called wombat.

My plan is to run "strace wombat", "strace evolution-mail" and
"strace evolution-addressbook" in separate terminal windows.
The evolution process can then be started normally.  

My observations so far lead me to suspect a problem with
wombat.  If any of you other Evolution uses would care to 
help me with this testing, please do!

Thanks,
	Miles

What state are the tasks in when it hangs, S, R, D, N, T, what?  I have
an intermittent problem on 2.4 where an entire process group goes into
T state even though nothing is tracing it.  Killing the offending
process then sending SIGCONT to the rest of the process group restarts
the group.  The offending process is usually the last one on the tree.
