Comment # 18 on bug 1231578 from Clemens Famulla-Conrad

I can confirm that suspend to disk fail with kernel 5.14.21-150500.55.83 on a
Latitude 7480 with LEAP-15.6 installed. 
Thanks for the report!

Following kernel versions worked for me:
6.4.0-150600.21-default (36c1e09)
6.4.0-150600.23.25-default (ea7c56d)
5.14.21-150500.53-default (b630043)
