I attempted this and booted into kernel 5.19.0-32-generic however I then had no wifi at all. The option to connect no longer existed in the top right corner.
Prior to this, it failed in the same way, with Microcode SW error detected, a second time today. It does seems like it happened less often but it's hard to prove that. I switched back to 5.15 for now so as to have a usable computer. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2007875 Title: Ubuntu 22.04 XPS 13 plus 9320 kernel 6.0 OEM and 5.19 breaks wifi frequently Status in linux-firmware package in Ubuntu: Fix Released Status in oem-somerville-tentacool-meta package in Ubuntu: Invalid Status in linux-firmware source package in Jammy: Fix Committed Status in oem-somerville-tentacool-meta source package in Jammy: New Status in linux-firmware source package in Kinetic: Fix Released Status in oem-somerville-tentacool-meta source package in Kinetic: Invalid Status in linux-firmware source package in Lunar: Fix Released Status in oem-somerville-tentacool-meta source package in Lunar: Invalid Bug description: [SRU Justification] [Impact] backport-iwlwifi-dkms/kinetic is being built into hwe-5.19 kernel, and -73 firmware are supported bug missing.

Recently I received some kernel updates, the 5.19 kernel used in 22.10 and a 6.0 oem kernel. Both updates break wifi. It seems to only do so on newer 5.7 GHz access points. 1. Boot latest 6.0 oem kernel 2. Browse the web, usually takes between 1 and 5 minutes. 3. Networking will cut out. Disabling networking and starting again will fix it until it happens again in a few minutes. This will repeat indefinitely, essentially making wireless useless. The attached dmesg log reliably shows up when it fails, showing iwlwifi failing and a (network?) hardware reset request. It witnessed this happen months ago on 22.10, which led me to using the Dell stock 22.04 image. But it seems even the newer OEM kernel is affected. A workaround is to select the older 5.15 kernel in grub. I find on this laptop, one must hit escape precisely 1 second after seeing the Dell logo on boot. Alternatively one could edit /etc/grub/default and set a longer timeout. Let me know if this bug report would be better to go to Dell as a support request instead.
