Is it with Intel WiFi?  If yes, there is a known regression up to 5.7.1 (boo#1172905).

I have a Realtek WLAN adapter:

brix:~ # hwinfo --wlan
05: PCI 200.0: 0282 WLAN controller                             
  [Created at pci.386]

  SysFS ID: /devices/pci0000:00/0000:00:1c.2/0000:02:00.0
  SysFS BusID: 0000:02:00.0
  Hardware Class: network

  Vendor: pci 0x10ec "Realtek Semiconductor Co., Ltd."

  SubVendor: pci 0x1a3b "AzureWave"
  SubDevice: pci 0x2161 
  Driver: "rtl8821ae"
  Driver Modules: "rtl8821ae"

OK, then it's a different problem.

Does the old 5.6.y kernel still boot fine?  If yes, please give the full hwinfo output.

Also, when you boot without quiet and splash=silent options, it might show more logs.

I'm running on 5.6.14-1-default at the moment.

Booted 5.7.1 without quiet and splash.

> hwinfo --short:

Could you run hwinfo without option, and upload the full contents to Bugzilla (use attachment, not pasting to the form)?

And try to pass "nomodeset" boot option.  This will stop switching to the native Intel graphics and keeps EFI framebuffer.  If it's a problem in i915 driver, this should make the system booting further.

Excuse me I'm late. I've just tested the nomodeset option and I succeeded. With nomodeset 5.7.1-1-default is bootable.

Thanks, that's at least a good step forward, we could narrow the range.

Could you try the latest kernel in OBS Kernel:stable repo?  It contains the newer 5.7.x kernel, and a bug might have been already addressed.

If the problem persists, we need to report it to the upstream devs.

The problem persists with 5.7.2-1.2 and 5.7.4-2.1.g23bad63 from https://download.opensuse.org/repositories/Kernel:/stable/standard/x86_64/.

OK, then it's time to report to upstream.
The upstream bug tracker is on gitlab.freedesktop.org
  https://gitlab.freedesktop.org/drm/intel

Open an issue ticket there.

Bernhard, have you opened the ticket upstream? Could you provide a link, please?

TW also got 5.8.x kernel meanwhile, so it would be nice to know if it improved things.

I'm sorry I can't check the problem anymore because my Tumbleweed crashed and I changed to CentOs.

I did not open a ticket upstream.

Pity, but thanks for letting us know. Closing.
