It always seems to happen doing the same thing though: (i.e., I
display various fields on the screen, when reading new data I display
dashes in the fields and "Reading" at the bottom of the page, and the
crash always happens at that time).
I am no Linux expert, but I think it should be impossible to freeze the
kernel with a wild running "userland" application.
My thoughts exactly
I still think it is
somehow hardware related.
It could be, but since it happens also on a completely different
machine, with different processor, memory, video and an onboard serial
port instead of the usb adapter, maybe it's an obscure kernel bug that's
triggered only under some special conditions :-(
You could run your application in several virtual machines parallel. May
be you could use a different Linux distribution/kernel version. The host
pc (for the hypervisor) should work reliable of course ;-)
Maybe that could be the only way to see where it hangs (if it happens to
hang on the virtual machine).
I'll see what debugging options VirtualBox has.
