I am using Ubuntu 22.04 kernel 5.15.0-160. It failed to boot after installing the TBS5927 linux driver patch, but the old kernel 5.15.0-157 still works.

I followed instructions on their site, but it seems something is wrong. They didn't provide instructions on how to uninstall, and for now I manually boot the old kernel from GRUB every time, but I want to restore the system to the previous state or better to fix the error and use TBS5927.

Last line before the kernel stopped is

audit: type=1326 audit(1761286693.927:234): auid=4294967295 uid=0 gid=0 ses=4294967295 subj=snap.cups.cupsd pid=3432 comm="cupsd" exe="/snap/cups/1112/sbin/cupsd" sig=0 arch=c000003e syscall=93 compat=0 ip=0x7f94fcd14b0b code=0x50000
