Apparently the kern.log just shows boot, adding syslog excerpt with the kernel messages
** Attachment added: "syslog-excerpt.txt" https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1937415/+attachment/5513209/+files/syslog-excerpt.txt -- 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/1937415 Title: Intel Wi-Fi 6 AX200 (iwlwifi) unstable with linux-firmware 1.199 Status in linux-firmware package in Ubuntu: New Bug description: After upgrading from linux-firmware 1.198 to 1.199 my connectivity became unstable and I could see repeating hardware resets in `dmesg` output. Downgrading to linux-firmware 1.198 again resolved the issue. Note: this bug was filed after downgrading the package, but hopefully apport would have caught the kernel logs from previous boot as well.
