Soft lockup on boot with linux 6.10.6.arch1-1

Description:

I upgraded my laptop to the latest kernel (linux 6.10.6.arch1-1) on Tuesday August 20 and upon reboot my machine got stuck after unlocking the LUKS partition. The last message on the user-visible boot log is a successful fskc of the root volume.

Reading the boot log via journalctl after chrooting into the broken system from USB install media showed a soft lockup, seemingly somewhere in systemd-udev

Installing the LTS kernel (linux-lts 6.6.47-1) and regenerating my grub config to boot into it allowed me to use my computer again.

Additional info:

• Purism Librem 14, Intel Core i7-10710U, 48Gb RAM, Samsung Evo Plus 970 SSD
• CoreBoot BIOS
• grub bootloader, plain /boot partition
• LVM on LUKS (root, home, and swap in logical volumes on the same encrypted partition)

linux 6.10.6.arch1-1 is broken, linux-lts 6.6.47-1 works
