Hi,

I am trying to debug my USB Gadget driver. I have two machines connected to the LAN and the driver is running on one of them. However, there is no serial or ethernet null-modem connection between them.

At some point in time, the kernel freezes due to my buggy driver (I am suspecting unreleased lock) In this situation I need to be able to reboot the frozen host remotely from the other host.

I searched on the net and on the forum but did not find material which would serve this purpose, although I found a few useful tutorials on KGDB:

Please let me know if there any way of doing this.

Thanks for your time!

Maybe something like User Mode Linux? http://user-mode-linux.sourceforge.net/
Running the kernel in a virtual machine should help you finding the bug, because you'll be able to find out where it is.

Thanks for responding.

I thought of UML as a way out but the issue is I am using PCI based Net2280 USB device controller on top of which I have written the USB gadget driver. UML doesn't support PCI emulation (I guess, please correct me if I am wrong). Same is the case with virtual machines - VMWare and Virtual Box. So I need to be able to debug it on the host itself.
