Kernel panic when usb wlan adapter is connected during boot

[Saddy]

Hello,

the adapter is an OvisLink Corp. Air Live WLAN USB device. If the adapter is connected after booting, it is working fine.
See attachments for a foto of the panic and kern.log.
These are the different modules loaded before and after connecting the device:

$ diff lsmod.txt lsmod.txt2

< usbserial 39780 5 option,usb_wwan
---
> usbserial 39780 4 option,usb_wwan

(I think the ppp module is due to the UMTS modem also connected with the network-manager).
