microcode-20201110 hangs and does not boot
tugboat-maguire opened this issue · 4 comments
I have a Lenovo Yoga 710-11ISK laptop. The computer has an intel m3-6Y30 processor.
I am using ubuntu 21.04. The computer does not boot after 3.20201110.0ubuntu1 microcode update. It says "Loading initial ramdisk".
I am able to boot if I select an older kernel in the grub menu or if I enter ubuntu recovery mode.
$ dmesg | grep microcode

I am unsure what logs are useful. Please let me know if there's other information I need to provide

New revision 0xea of 06-4e-03/06-5e-03 microcode files has been published as part of microcode-20210608 release, it may be worth to try it out.
The 20210608 release solved my issue
