Hello > the kernel config already has > CONFIG_LOCKDEP_SUPPORT=y > Is that what you meant? Does it need any extra to activate? LOCKDEP_SUPPORT mean that LOCKDEP can be enabled on cpu architecture for which kernel is build. To enable it you have to use "make menuconfig" and mark up "Kernel hacking ---> Lock debugging: prove locking correctness" After that CONFIG_LOCKDEP=y should show up in .config. > meanwhile I had a similar bug on rc6 hours after resuming. > > This time it had some additional soft lockup messages ontop. see > http://www.zq1.de/~bernhard/temp/dmesg.bug Again, lockdep should print more information and allow to debug this easly.
