Can you attach dmesg messages so that we can know what exactly the error is? >=20 > I bisected this to commit 5aec989, which first appeared in 5.15-rc6.

Note: when you refer commits, write at least 12 first characters of the commit's hash. You may want to set `core.abbrev=3D12` in your `~/.gitconfig`. Also the canonical commit reference is `--pretty=3Dformat:%h (\"%s\")`. And remember: when replying, don't top-post; reply inline with appropriate context instead. Anyway, I'm fixing up the title: #regzbot title: Realtek ALC236 unrecognized on reboot Thanks. --=20 An old man doll... just what I always wanted! - Clara --8XX5bEJKjbAtICQ4 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQSSYQ6Cy7oyFNCHrUH2uYlJVVFOowUCZGB0bAAKCRD2uYlJVVFO o1hEAQDXt2gGeCFUztxgePc09xdG10X7dIku2mCPwiSgw15SZAEAgMPt04I1v1c1 4gDr+jnM3a3nNlxhPoHiPrNH7KIcGwA= =ACa/ -----END PGP SIGNATURE----- --8XX5bEJKjbAtICQ4--
