You can check that in U-Boot that the control device tree has the new setting: fdt addr $fdtcontroladdr fdt print For measuring the actual speed I used package glpk-utils. I measured the execution time of the command glpsol -m /usr/share/doc/glpk-utils/examples/tsp.mod I suggest to check both before and after upgrade. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1941622 Title: [SRU] Bump unmatched CPU clock rate to 1.2 GHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/u-boot/+bug/1941622/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
