WiFi broken after Firmware Update

I have updated my Precision 5530 yesterday to Firmware 1.11.2 (via DELL's Windows update tool)

I am running dual boot while using windows only for firmware updates and some specific tasks. The main OS is debian 10. The firmware update now broke compatibility with the iwlwifi driver on my debian 10 system running kernel 4.19.0-5-amd64:

[ 38.834845] iwlwifi 0000:3b:00.0: SecBoot CPU1 Status: 0x3, CPU2 Status: 0x23f5
[ 38.834848] iwlwifi 0000:3b:00.0: Failed to start INIT ucode: -110
[ 38.848934] iwlwifi 0000:3b:00.0: Failed to run INIT ucode: -110

The other ACPI Errors are 1 year old and I don't think they are related.

No wifi is a real deal breaker. This error should be fixed or reverted to the old firmware state asap. I don't feel like DELL is putting much love in its linux compatibility of the Precision series.
