I would recommend to add the following options to the kernel config: options STACK options DDB options DDB_NUMSYM options KDB options KDB_TRACE options KDB_UNATTENDED (if you don't have any of them already). That should add some useful information to the panic messages. Please try to capture the first panic report before any secondary panics cloud the situation. And I agree with Alexander that the panics and the hangs could be unrelated. -- Andriy Gapon
