Hi,
i have a problem with driver for my usb modems. Time after time server stuck(
log from this event is below), in this case server has to be rebooted. I think
that this could be caused by any condition that cannot be occured.
Can you take a look for it or give me some tips to solve this problem?
Name of modemes is GlobeTrotter GI1505 and the whole description is in attached
in mail.
The version of my kernel is 3.6.11 on debian linux.
Can you try 3.7.9? A number of tty issues have been fixed since 3.6.11
that might be the cause here.
thanks,

Hi,
i`ve tried kernel version 3.8.2 as you advised. But there is the similar
problem as i`ve described in last mail.
Can you take a look for it?
