This happens on a new Lenovo X1 Yoga - 4th generation (2019). As a result of this, the wifi is unusable.
The Wifi seems to work with the F30 Live Image, which has kernel-5.0.9-31 and linux-firmware-20190312-94. Here's the output of lspci related to the Wifi adapter: 0:14.3 Network controller: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] (rev 11) Subsystem: Intel Corporation Device 0030 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at ea238000 (64-bit, non-prefetchable) [size=16K] Capabilities: [c8] Power Management version 3 Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [40] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [80] MSI-X: Enable+ Count=16 Masked- Capabilities: [100] Null Capabilities: [14c] Latency Tolerance Reporting Capabilities: [164] Vendor Specific Information: ID=0010 Rev=0 Len=014 <?> Kernel driver in use: iwlwifi Kernel modules: iwlwifi

So this would seem to be a combination of kernel and firmware?
*** This bug has been marked as a duplicate of bug 1733369 ***
The firmware update in Bug 1733369 seems to resolve this issue, so I'm closing it as a duplicate of that Bug.
