Hello...
I am having a problem with my TSSTcorp CD-RW/DVD-ROM TSL462D. The error
below is causing a parallel application to fail. Here is the relevant
output of my system log (dmesg command)

I have noticed that when i run a parallel MPI application with more than
one thread per machine, the problem is triggered... I also have
noticed that
the prompt above comes from the HAL daemon because when i disable the hal
daemon, this is not prompted anymore but the problem persists. Using the
acpi=off kernel option, the system tends to be more stable but the
problem
does not solve...
Here is my system info (uname -a):
[waldyd@nodo5 ~]$ uname -a
Linux nodo5.gialea 2.6.23.14 #1 SMP Mon Feb 4 16:12:24 COT 2008 x86_64
x86_64 x86_64 GNU/Linux
Any ideas about why is this happening? How can i solve this?
Try upgrading to the 2.6.24 kernel. That fixed this sort of problem for me.
