Sorry if was not clear. =C2=A0Only 6.19.4 has kernel crash.=C2=A0 The summary is: =C2=A0- 7.0-rc1 - no kernel issues =C2=A0 =C2=A0 boots fine and does not crash when nftables is invoked. =C2= =A0 =C2=A0 =C2=A0 But, It has an nft error and fails to load rules with older nftables userspace. =C2=A0 =C2=A0 Same rules load fine using updated nftables. - 6.19.4 - crashes whenever nftables is invoked. =C2=A0 Does not matter which userspace nftables is used, older or newer - 6.19.3 - works fine. I will report back soon as have finished testing 6.19.4 with commit f175b46d9134 gene --=-tekoYUGGf0I8LLXeH7Nc Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iHUEABYJAB0WIQRByXNdQO2KDRJ2iXo5BdB0L6Ze2wUCaaGjQAAKCRA5BdB0L6Ze 24UaAQDbPXEelXLbkvRWyKgoR0AYWf/ndrCSqX9i6GoxdpMgGgEAtls3HDvuRRX8 pw/zKud5eE0bLP/KXF6p85VESPHWNww= =DbbN -----END PGP SIGNATURE----- --=-tekoYUGGf0I8LLXeH7Nc--
