    Yeah I know. I removed them. Simply posting for more info.

    A more performant alternative to AF_ALG... https://github.com/cotequeiroz/afalg_engine
     
    Not a solution to your issues unfortunately.
     
    IIRC, there was a way to overclock the helios to 2.0ghz or 1.8ghz. Don't remember the details.

    Is it me or it the mv_xor driver being loaded late?

    I see that /proc/interrupts shows no action despite me using RAID5.
     
    edit: from looking at kernel source, it seems btrfs uses xor_blocks instead of async_tx. The former seems software only.

    Progress update: kernel 4.19.70 fails. .65 works. Testing .67 now.
     
    edit: .66 has not crashed yet. Will wait to see if it can stay alive for 12 hours.
     
    I'm trying to compile kernels based on commit. It doesn't seem to work though. I'm trying

    Which gives

    I'm trying to see which commit is responsible for the failure based on https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=v4.19.158&ofs=9800
     
    Current theory is this commit: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v4.19.158&id=46b306f3cd7b47901382ca014eb1082b4b25db4a
     
    It says it's for 32-bit.

    I found the issue. It's some local armbian patch that messing things up.
     
    I recently cloned https://github.com/armbian/build and removed 5 pointless patches. That PR was merged. So I built that and same issue.
     
    Then I deleted a bunch of patches from the mvebvu-current directory.
     
    So far with this kernel, I am not getting any issues. My git status currently is this:

    ```
     
    My theory is that the pci patch or one of the GPIO ones is causing the issue.
