Okay, I'll raise the issue there (if not already done).
So the outputs are:
$ iucode-tool -Sv
iucode-tool: system has processor(s) with signature 0x000906ea
iucode-tool: assuming all processors have the same type, family and model
$ lscpu
Architecture:x86_64
CPU op-mode(s):
Thanks for testing and sorry you're experiencing this. Can you confirm
that the output of 'iucode-tool -Sv' contains:
iucode-tool: system has processor(s) with signature 0x000906ed
output of lscpu would be useful too, along with ensuring you have the
latest BIOS installed from Dell.
Raising
Correct, Ubuntu 20.04 LTS/focal.
Results of upgrading intel-microcode package to 3.20200609.0ubuntu0.20.04.2:
1) First reboot was successful (without dis_ucode_ldr flag)
2) Second and following reboots froze again, the behaviour is now the same as
stated in #1883002.
3) Workaround: Grub's
This is on Ubuntu 20.04 LTS/focal, correct?
If so, this is either exacerbated or triggered entirely because focal's
intel-microcode package enabled late loading of microcode (known to be
risky) that would get triggered while updating the intel-microcode
package itself; see LP: #1883002. Even
$ dmesg | grep microcode
returns nothing
Note: Grub can only boot with 'dis_ucode_ldr', please find the attached
picture of the failure using 'nosplash debug' flags.
** Attachment added: "The point of failure"
Can you please post the output of:
dmesg | grep microcode
thanks
