I've been bitten by X not recognising the appropriate chipset, although this may well be a poor xorg support once-upon-a-time thing. And I compile that from source too .. (normally) .. but perhaps not bleeding edge enough ..Don't you use Gentoo normally? That kind of implies "I built in from source" does it not! :] I build my own too (debian style though, so I really do have to checkout Linus' tree from git, merge a bunch of patches manually, fix some stuff, compile yet more stuff in-tree and pray really hard as the debs build). Are you on 4.19 yet? I'm having serious issues with the recurring "Warnings from objtool while compiling the 'icp' kernel module: "unsupported stack pointer realignment"" bug: https://github.com/zfsonlinux/zfs/issues/6950 Annoyingly 4.19 will build and install clean until ZFS modules enter the picture and because my root is on ZFS, that's not good. 4.19.0-pf3 (my upstream patchset) is out today so I'm building another one right now and if that doesn't work my job tonight is to dig into the Gentoo and Arch sources to see if it's resolved there... ghost@failbot:~/SRC/linux$ cat /proc/version Linux version 4.18.0-pf10-meowski+ (ghost@xxxxxxxxxxxxxxxxxxxxx) (gcc version 8.2.0 (Ubuntu 8.2.0-1ubuntu2~18.04)) #1 SMP Sat Oct 20 18:23:30 BST 2018 CheersI'm being a right dinosaur here actually, and I'm sitting on mainly LTS 4.4 branches or 4.9. I'm long overdue a major system overhaul, but not sure which way I'll go yet. I have had some issues with the meltdown/spectre patches on one system, so I've had to revert. I'm now running the ck patchset, which makes a noticeable difference in performance/memory usage. Next step is to change C library over to musl .. but that is a longer-term plan, depending on when this Big Overhaul takes place .. That said, I am loosely involved in the Gentoo kernel project, and am working on the new CI framework for it, so I have access to some clever people. Alas Greg K-H left Gentoo after the last hiatus (-sigh-) .. so we can't poke him directly so easily any more. MJE #zfsonlinux on Freenode IRC might be a resource to tap into. MJE |
