Perhaps we can get some logging that way. I enabled the following options: CONFIG_LOCKDEP_SUPPORT=y CONFIG_LOCKDEP=y CONFIG_DEBUG_LOCKDEP=y CONFIG_DEBUG_SPINLOCK=y CONFIG_DEBUG_MUTEXES=y But it didn't detect any lockup yet, and machine still hangs. I'll try CONFIG_PROVE_LOCKING. Enabling CONFIG_DEBUG_INFO seems to make the problem go away... > > Have you tried the vendor's driver from www.realtek.com?
