Hi all again, I found this kernel panic past days, now using the unsuported kernel and comes out again the same error. This time on '2.6.9-22.0.1.106.unsupported' kernel See attached logs, Env is the same with the same box, Hope it helps. TIA.

I'm not sure if it is due to the usb2serial adapter but i think so because no panic in that system before. To reproduce it: a) In a gnome-terminal im executing a bash script like this: FILE=/root/dump rm $FILE stty cs8 ignbrk cread clocal raw 4800 -echo $1 < /dev/ttyUSB0 killall cat cat /dev/ttyUSB0 | tee $FILE & cat > /dev/ttyUSB0 ; kill %% b) The other side is a modem with an available console via serial line where i connect the USB2serial cable c) From the modem power-on i start detecting hard font corruption in gnome-terminal, if i break the link (CTRL+C) and i perform the '$ reset' command, everything comes back ok, but after connecting again using the script im having the same thing if the modem restarts (no matter if there is a modem hard reset or sw reset, i mean, power on all the time in the modem) d) After few 'resets' in gnome console, the kernel panic is happening. Don't know where to send this panic, im sending it to this list, feel free to tell me if i have to inform others or use other reporting tools for kernel panics... help appreciated.
