I have an issue with USB 3G modem on SLES 11 SP4.
When I unplug the USB Modem or resetting it from the console the server goes to reboot.
On SLES 11 SP3 I don't any problem and modem working without any issue.
I am using usb_modeswitch to get modem works.
Resetting the modem with the command
usb_modeswitch -R -v 12d1 -p 1506
This command works ok on SLES 11 SP3
But when I run this command on SLES 11 SP4 the server going to reboot.
