same for me
X locks but I still can login per ssh
the process ent.sda5! uses almost the whole cpu
/ is /dev/sda5
I´m using kernel 2.6.14-rc4 and reiser4patches from 2.6.14-rc2-mm2 +
reiser4-add-put_inode.patch
so long

Hi,
Since updating to 2.6.13.2 last week I've had a couple of system hangs
which required a poweroff. I can now reproduce a bad performance +
can't reboot situation. I'm using gentoo with a reiser4 root
partition. I've only tested this on my own system, so if another
2.6.13.2 + reiser4 gentoo user could try this that would be useful.
Under 2.6.12.5, do 'time emerge =sun-jdk-1.5.0.05'. Total time is 2
minutes 10 seconds.
Under 2.6.13.2, do 'time emerge =sun-jdk-1.5.0.05'. Total time is 6
minutes 51 seconds. Will appear to hang at the "gzipping man page:
unpack200.1" but eventually finishes. After this, attempting to
shutdown will result in a system hang.
Like I said, this happens every time I emerge that package. Probably
it causes some pattern of disk I/O that triggers a bug in reiser4.
During the hang time, the pdflush process is taking up most of the
cpu, and there is almost no disk i/o. I tested with a non-preempt
kernel, and get the same. With 2.6.12.5, everything is okay.

I'll confirm this. Problem is, I think this was with the mm patch, and
I tried the standard patch, which refused to compile. I'll send a more
detailed bug report later, but pretty much -- hang (after much longer,
the install phaze of a glibc compile), the rest of the system seems to
keep functioning, but shutdown doesn't work. Don't remember if it was a
single program hanging forever or an actual kernel panic.
I don't have all of my Reiser4 machines available at the moment, I'm on
an OS X laptop. Some are ssh-able, but some are physically off.

Hi,
I can confirm this problem :
Process or System hang during depmod -> need hard shutdown to get out.
Tested on 2.6.13, 2.6.13.2 , 2.6.13.3.
No problem with 2.6.13mm3.
How to reproduce it : Install the latest Nvidia driver.
No logs.
Best regards
JP

Interesting...I also have problems with Reiser4, 2.6.13 (I use archck8
however) and NVIDIA...
X just locks up unexpectedly. Don't know if it's related but who
knows...
I don't have any logs either. How can we troubleshoot?

I've had X lock, but I use ATI drivers.
