Hi,

I'm having a problem with 2.6.12-rc3 and the Java VM (from SuSE 9.2)
on AMD64.  Namely, after trying to open a web page containing a Java
applet, my browser starts a java process that takes almost 100% of the CPU
(system load, according to gkrellm) and cannot be killed (even by root,
although it executes with a non-root UID).  Apparently, it is in TASK_RUNNING
(according to ps).

The problem is 100% reproducible (it is enough to visit
http://java.sun.com/docs/books/tutorial/getStarted/index.html to trigger it)
and it does not depend on the web browser used.

The Java JRE version is:

java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)

(I guess it's 32-bit, but I'm not quite sure) and I've installed it from the
SuSE 9.2 RPM.

It really is a show stopper to me, so please advise.

Greets,
Rafael

Where is it running?

You can tell this from a kernel profile, or by using sysrq-P five or ten
times then looking at the output.

all the time.

I've also found out that in fact the problem is not 100% reproducible, but it is much
more likely to be reproduced if the CPU is heavily loaded.

Greets,
Rafael

All the time?  Exactly the same?  If you could do something crude like hit
sysrq-P 100 times then do `dmesg|grep RIP' we could possibly determine
whether things are indeed stuck in that potential infinite loop in there.

I assume you're using CONFIG_PREEMPT?

It'd be interesting to know the interrupt rate and context switch rate
which this is going on.

OK, the result is attached (I think things really are there).

No ...

OK, but could you please tell me how to get these numbers?

My mind tells me this might be the problem but statistics also tell me
processes should get stuck all the time here...

In retint_signal %rdi is destroyed, need to jump to the label above
retint_check that sets %edi back to $_TIF_WORK_MASK

Hi!

I'm also having the above problem with debian sarge, 2.6.12-rc3,
blackdown java 1.4.2 (also sun's 1.5.0), and preempt is not enabled.
Attached my kernel config. The problem arises not with every java
applet, e.g. www.playsite.net online gaming applets wotk fine, but the
gportal.hu site kills the system, only xfree's mouse cursor is
responsing, no alt-f1, no acpi button.

Feri

No.  It is exactly _one_ Java process that _does_ _not_ _react_ to kill -9.  Apart
from this, the system is responsive and the other processes get their CPU
share as usual (eg if I run another process that normally would get ~100%
of the CPU, now it gets 50% of it and the rest is "used" for the Java).

It looks like a kernel bug to me this time.

Which kernel works? Have  you tried a stable one? (2.6.11.7 is recent)

Readd missing clis in the interrupt return path.

Yes, it does, apparently (ie I'm unable to reproduce it). :-)

I assume that the Alexander's patch is not needed with this one?
