Public bug reported:
Hi,
I am using Ubuntu/Lucid on a IBM/Lenovo Thinkpad T61. A umts usb modem from
Sierra Wireless is integrated.
When I use a application, which make use of the CnS device (ttyUSB1) my laptop
crash. Unfortunately my application
crash with a segmentation fault after a few seconds after starting. A few
seconds later the laptop crashes completely.
This is the output of AT command ati:
Manufacturer: Sierra Wireless, Inc.
Model: MC8775
Revision: H1_1_8_3MCAP C:/WS/FW/H1_1_8_3MCAP/MSM6280/SRC 2007/03/08 18:17:59
IMEI: 352678013064321
IMEI SV: 6
FSN: D282407462010
3GPP Release 5
+GCAP: +CGSM,+DS,+ES
Attached is the kernel oops I got via serial connection to the laptop.
The laptop runs in a docking station.
The same problem exist in Ubuntu/Karmic. The problem does _not_ occur
with Red Hat 5.2 on the same hardware.
Any help is appreciated.
