Hello, we are happily using 3 supermicro hosts in pool with 10G shared iscsi storage. Hosts have different configurations witch latest BIOS.


host1 - Supermicro X8DTN, Xeon X5650, areca 1680, Supermicro STG-I2 (intel 82598EB)
host2 - Supermicro X9DRH, Xeon E5-2630 areca 1222, Supermicro STG-I2 (intel 82598EB)
host3 - Supermicro X10DRi, Xeon E5-2640, areca 1226, Supermicro STG-I2 (intel 82598EB)


Last weak I upgraded pool from XS 6.2 SP1 to 7.0 with all hotfixes. After couple of hours trouble-free and fast operation, all 3 hosts starting to freeze. There is nothing on console and no crash dump. After hard reset I saw the error (attached). Only after turning on/off the server boot again.

Only mutual hardware is the 10G STG-I2 Cx4 card used to iscsi SAN connection.


With Xenserver 7.1 there is same problem.


After downgrade to Xenserver 6.2 SP1, everything works fine again.


Any advice will be appreciated.


With regards
