Hmm, same problem - either that log is missing the crash details or we
have a new similar bug in kernel 5.11. Regardless it's probably safe to
say the original bug in kernel 5.8 won't be fixed since that's now been
officially replaced by 5.11. So whatever the issue is in comment #42/#40

I was gone on Friday after 3:00 PM and all of Saturday and my first

Thanks. The log in comment #40 shows the system sleeping but never
waking up again. It's not clear if that's the same bug and just missing
log entries or a new bug. To help us figure it out please try:
1. Suspend.
2. Open the lid.
3. Wait 10 seconds.
4. Reboot or REISUB.
5. Run this command:

Thanks Daniel. I think 5.11 kernel locks up as well but I'll test it

Also I have booted 5.11.0-25 and the system locked up when I lifted the

I'm hoping the official update to 5.11 is enough so the suggestion in

Oh I didn't realize Ubuntu 20.04 has a version of libc that's a little
too old for that. You will need to try an older kernel version that's
still newer than the 5.8.0 that caused this bug. Maybe try:

Yes we do need to make this process easier for people.
1. Download these four files:

How do I install these files, I'm not that conversant with Linux.

Had another crash and unlike bug 1917674 the keyboard won't respond at
all. I tried the ALT SYSREQ (prt sc) REISUB and REISUO and nothing
worked. Any comments Daniel?
