Unfortunately that's not working for my system. After installing TW kernel, I can no longer boot into my system on encrypted LVM, that's just working with the current 15.2 kernel.
That's bad. I don't know of such an issue, maybe some problem with initrd. Do you get the emergency shell? In the worst case, you can try some TW Live image. We want to see only whether the suspend/resume works, after all. -- You are receiving this mail because: You are on the CC list for the bug.

So far my tests on 15.2 with 15.1 kernel are successful - I have not seen any crash.
OK, at least it's a good news. Leap 15.1 kernel is based on 4.12, but the WiFi stack and iwlwifi driver are almost equivalent with 4.19. There are a few other older kernels available in OBS home:tiwai:kernel:4.19, home:tiwai:kernel:4.20, home:tiwai:kernel:5.0, home:tiwai:kernel:5.1 and home:tiwai:kernel:5.2, corresponding to each kernel version. If you can find out which kernel starts regression, it can be a great help.
Since I do not have an account on kernel.org, I'd appreciate if you can move that issue there.
Then you can report to linux-wireless ML instead, too. This can be even a better path :) But it'd be better to narrow down the regression at first. -- You are receiving this mail because: You are on the CC list for the bug.

Not sure if it is related but maybe worth mentioning also, i had a problem with networking after a resume which i solved with a workaround. It was systemd-networkd related: https://github.com/systemd/systemd/issues/14987 Maybe it can be of use in this case also, aside the problem with the driver loading.
Did you - with your problem - see any similar crash in dmesg as in my logs? -- You are receiving this mail because: You are on the CC list for the bug.
