I have upgraded to OSX Yosemite from Mavericks 10.9.4 and a very weird problem is happening. I use a Hostless Wimax USB Modem from Qubee (Wimax ISP from Bangladesh) for internet. So, there's no driver or connection manager has been required so far so use it. It has been working pretty good so far in all operating systems I use.
But After upgrading to Yosemite, If the modem is unplugged by hand or disconnected or even a very negligible disconnection happens, My Mac gets a obvious Kernel Panic and without a restart it can't be used.
Has anyone faced similar problem like this ? or any idea about it's solution. In this moment a clean installation of Mavericks is too much time killing for me.
Crash Log is as follows :

A kernel panic in most *nix operating system is very difficult to debug. You can get hints from here how to submit a bug report http://support.apple.com/en-us/ts3742 but if you read the tech notes in the end of the article it points hints to either the OS kernel or driver causing the system to crash. The "quickest" workaround is to revert to the previous working state which unfortunately in your case is Mavericks. Sorry.
