Comment 38 for bug 1848771

A similar case for Linux Mint 19.3 Tricia
after upgrading to the new kernel i.e. 5.3.0-26-generic
no switch to suspend option ...
Only hard reset helps .... in logs nothing specific can be found except for entries:
Jan 18 12:05:08 kris-R780 kernel: [49.932794] PM: suspend entry (deep)
Jan 18 12:06:09 kris-R780 kernel: [0.000000] microcode: microcode updated early to revision 0x11, date = 5/8/2018
on earlier kernels the suspend option worked OK

4.15.0-54-generic - OK
4.15.0-72-generic - OK
4.15.0-74-generic - OK
5.0.0-32-generic - OK

5.3.0-26-generic - ERROR ! ( suspend )
