Subject: DEBUG_LOCK_ALLOC causes hostap kernel lockup

The lockups seem to be down to DEBUG_LOCK_ALLOC (Lock debugging: detect

incorrect freeing of live locks). If that is enabled then after enough

iperf runs the kernel will lock solid. This problems seems to happen in

kernels from at least 2.6.22 onwards.


I had no idea that enabling lock checking could itself result in a lockup...
