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.

Hi all,
Running a Centos 4.2 default config in a P4 1.7 Mhz 512 MB Usb 1.1 (Acer Aspire
1400 XV Laptop) with a usb2serial interface plugged from the system boot, and
using that line as console line for a remote device, i had the following kernel
panic after few times performing the "reset" command in the gnome-terminal due
font corruption, i had this kernel panic:

Dec 14 23:58:10 smarteyebox kernel: <0>Fatal exception: panic in 5 seconds
Dec 15 00:11:05 smarteyebox syslogd 1.4.1: restart.
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.
TIA
Jose.
