Yes, I was also affected by that (i.e. #1862751) and at the time had to revert to a previous microcode version while running bionic.
There is a difference, however, in that 1862751 only happened when running on battery (which is why I tested the two scenarios above) In early May I upgraded to focal and everything has run fine since; I didn't even realize I was again using 0xca until now. Looking at the logs I noticed that the processor is already running 0xca by the time Linux boots, so by now it's probably included in the system firmware (there were a couple of new BIOS releases quite recently); I don't know if that can make a difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883002 Title: intel-ucode 20200609: hangs on Whiskey Lake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1883002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
