Kernel panic and disconnection of all connections after modifying iscsi targets
Hello
I'm having a problem with open-e DSS, an old one ( 1.32.DB00000000.2854 ) and a new one ( 5.0.DB46000000.3084 ). when removing or changing an iscsi target I can expect a kernelpanic. This is bad because after the panic I have to reboot my SAN and all virtual machines that are using targets from the san are broken with possible dataloss.
This is the dump from my logs:

Please help,
