Re: [Linux-hls-devel] Processes freezing up

[Tony L. <ton...@ya...>]

Hi Luca,

Thanks for the suggestions!

Yes, the kernel we are using does have the pre-emptive
kernel patch in it.

I removed the patch yesterday but had problems
building the driver for the custom PCI card we are
using(?) - I am looking at rebuilding it and then
running the test without the pre-emptive patch.

>Looks like someone is unblocking ...
I ran our application a few more times and observed
the  machine to freeze almost immediately after
starting it. Given your comment above, the only thing
that is running from the start of the program is the
real time clock interrupt read() inside an infinite
while() loop. It may be that the this is causing the
unblocking behaviour you interpereted.

On Monday I will :
- apply the debug patch from your last email
- uncomment the __DO_CLI__ macros
- disable the rtc interrupts in my application
- run my application

If the problem doesn't occur then the rtc may be the
cause. Otherwise I will re-enable the rtc and send you
the output of dmesg.

Following that test I will go back to getting the
kernel running without the pre-emptive kernel patch
and then let you know if the machine still freezes
(and send dmesg output if needed).

Thanks again for your help.

Tony
