There also was some case of a different panic which looked like below: [ 16.191583] BUG: unable to handle kernel NULL pointer dereference at 0148 [ 16.201096] IP: [] check_preempt_wakeup+0x137/0x270 [ 16.208349] PGD 0 [ 16.211201] Oops: [#1] SMP [ 16.214877] Modules

Moving to a Xenial kernel seemed to cure some affected systems, so we would assume it being fixed released from there. ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to

We look to have had a hard recurrance of this issue on the system. After much messing about we appear to have gotten some real stack traces. We see similar ones on a range of kernel versions in 3.13.0-* series: NULL pointer dereference at 0010 [ 15.316900] IP: [] rb_next+0x1/0x50 [

Testing the latest upstream kernel will tell us if this bug is already fixed in mainline. If it is fixed, we can then work to identify the commit that fixes the bug. An alternative would be to perform a kernel bisect, which will identify the commit that introduced the regression. However, that

Joe, this is a production customer environment, so no we can't test newer kernels. I'm also not sure why a new upstream version would be relevant since this appears to be a regression in released kernels? ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Changed in: linux
