At the tail end of the 6.0.X series of kernels, I was getting hardlocks on the Dell also (plus another machine running TW, but not a laptop - and is now using Ethernet) and this bugzilla ticket was opened: https://bugzilla.suse.com/show_bug.cgi?id=1206683 ; there was a patch added and all was well. To my untrained eye, that patch isn't included (by name) anymore so I'm wondering if this issue is back? Could just be that the patch code is actually in the kernel now.
