Why does linux reboot at Random when running my USB communication program
 

Hello all

I am experiencing a problem that I am sure is not a distribution problem as I am experiencing similar problems on both my RH9.0 and knoppix 2.4.26 boxes.

I am using a private usb kernel mode driver (developed by the company that made the hardware) for the low-level usb comunication. My program sends information back and forth from the hardware device a number of times during execution. The whole time that the program is running it does not have any memory leaks (per Etnus Totalview w/Memory debugging active). Does anyone know of maybe an error message that is getting thrown that I may not be catching that could cause a spontatnious reboot of the machine. (the reboots occur even when I run my program in user mode not in root). I have turned off the trap for CAD in the inittab file and I still get the same problem. Sometimes I can run the program all day long and only have one reboot, other times I get it every 10 minutes. Any help or ideas would be lovely. I would show my source but it is for Job so it is a closed source matter as this is part of some black box style software.
Not sure if it might be a problem but the kernel mode driver uses a ring buffer, and i haven't used one since college, so I don't remember if they are proned to memeory leaks or what.

Thanks for your help.

I had something like it ones, but it hanged my computer not rebooting it.
The problem was in the usb modules.


Perhaps the usb module you use does a reboot?

Are the correct usb modules loaded for your chipset?

yes we are using intel and via mobo so they require the uhci and the ehci and that is what we have loaded. so I am at a loss. Any other ideas.
