kworker and ksoftirqd stuck at max CPU

Even since an update a few days or maybe a week back, I have the problem that kworker and ksoftirdq are using the entire CPU (or one core of it anyway):

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
   10 root      20   0     0    0    0 R   47  0.0   4:35.58 ksoftirqd/1                                                                                 
   44 root      20   0     0    0    0 R   47  0.0   3:25.06 kworker/1:1

It lasts for about 10 or 15 minutes after boot and then it returns to normal.

Anybody know what's going on?
