Hi,
[1.] One line summary of the problem:
Kernel oops related to emulated(?) serial device using pl2303 and pppd.
[2.] Full description of the problem/report:
I get the following oops shortly after pppd begins using the ttyUSB0
device. After the case I cannot use ttyUSB0 and the pppd process sticks
in too (kill -9 is inefficient after the oops), so I have to reboot to
redial.
[3.] Keywords (i.e., modules, networking, kernel):
usb, serial, kernel
[4.] Kernel version (from /proc/version):
Linux version 2.4.22-grsec (buga@piccolo) (gcc version 3.3.2 20030908 (Debian prerelease)) #1 Thu Sep 18 21:23:04 CEST 2003

Can you try 2.4.23-pre8 and see if that fixes your problem?
thanks,

2.4.23-pre8 fixed that, so the serial emulation is working now.
How can I grove the serial baud rate? After I change the baud rate over
9600 bps in minicom, I see only the noise and cannot communicate with
the built-in modem of my phone. In the phone I can't force the
communication speed, so I have to use some software solution.
RTFM with a pointer to any relevant documentation is sufficient for me.
Thank for your help,
Gabor

"grove"? What does that mean?
Have you read the Linux Serial Programming HOWTO?

I have a different problem with the pl2303 module, but have
no clue where to search: I have an ericsson cradle that I
check repeatedly if a cell phone is plugged in or not.
I wrote a small program that sends AT commands to the modem
every few seconds, and when an OK arrives, everythings fine.
It is indeed fine, until I unplug the phone and insert it again:
The program writes the 'AT\r\n' correctly, and I do get an answer
of the right length, but the read buffer does contain only zeros,
although the right length is returned.
Some things get me out of this loop of hell:
o reloading the pl2303 module
o when I re-insert the phone, I get correct data about every
tenth try.
o minicom seems to do additional initialization that cures
the problem as well.
I looked through straces of minicom as well as the other programs,
but did not find any significant difference. I did also load pl2303
with debug on, and found that it receives the right values in its
internal buffer, but they are not getting out of the module.
Can anyone give me a clue where I should look next?
thanks
Simon

Does this happen on the latest 2.4.23-pre8 kernel? Does this happen on
2.6.0-test9?

I have got the same problem with my usb-towitoko (pl2303).
I had this bug with 2.4.20, 21 and 22
After reading, an oops appeared.

Again, try 2.4.23-pre8. Let me know if that fixes it for you or not.

Thats great, no oops!
But the libchipchard project doesn't work. After starting the chipcardd,
I get this error:
"Mutex destroy failure: Device or resource busy"
But that could also be a bug in libchipcard or libtowitoko.
