-address_space_map() returns valid pointer in the first hit, but it returns NULL on the second hit because qatomic_xchg(bounce.in_use, true) returns true, I think it should suppose to return false. this is the stack trace when it happens for the second time

-It seems virtqueue_packed_pop() receives one desc with desc.len=65536 (or -1) which should not suppose to happen. I dont know why this is happening"""
