Subject: [Regression?] Linux 5.19-rc5 gets stuck on boot, not rc4

Hi,

Linux 5.19-rc5 does not boot on my Kaby Lake Thinkpad.
rc3 and rc4 were still fine, so I guess something between rc4 and rc5
introduced a regression.

Unfortunately, there are no errors or warning messages.
It gets stuck quite early on boot, about the time USB is initialized,
so less than 1 second into post-bootloader boot.
It then just sits there doing nothing - SysRq still works though.

I don't have time for a bisect, but I thought I'll let you know about
this issue, and maybe someone already has an idea.

Some system information below. Root filesystem is f2fs.
