Ahh right, let me check that.

I actually have this same problem.
I'll send more details when I get home later.

I think the problem started for me after r302265.
Before that, I can set vfs.zfs.arc_max and vfs.zfs.arc_min in loader.conf.
After r302265, setting either vfs.zfs.arc_max or vfs.zfs.arc_min in loader.conf results in the EINVAL errors in 'dmesg':

Setting sysctl vfs.zfs.arc_max failed: 22
Setting sysctl vfs.zfs.arc_min failed: 22

But setting vfs.zfs.arc_meta_limit in loader.conf works fine.

But I did notice that using 'sysct' or sysctl.conf for vfs.zfs.arc_max and vfs.zfs.arc_min works.
I only have problems with setting them now in loader.conf.

Like I said, I'll try to send output from my setup later.

Thanks.

    What is it currently?

    Just had a quick play here:
    sysctl vfs.zfs.arc_max
    vfs.zfs.arc_max: 32283127808
    sysctl vfs.zfs.arc_max=32283127807
    vfs.zfs.arc_max: 32283127808 -> 32283127807
    sysctl vfs.zfs.arc_max=32283127808
    vfs.zfs.arc_max: 32283127807 -> 32283127808

    Error 22 = EINVAL so I suspect you're requesting a value which one
    of the following:
    * < arc_abs_min
    * > kmem_size
    * < arc_c_min
    * < zfs_arc_meta_limit

        Regards
        Steve

        Steven and -current:

        I just updated to r302350 with a GENERIC kernel config.  I see
        this in
        dmesg:

             VT(efifb): resolution 1024x768
             Setting sysctl vfs.zfs.arc_max failed: 22

        (3491.98-MHz K8-class
             CPU)

        The relevant parts of /boot/loader.conf are:

             zfs_load="YES"
             vfs.zfs.arc_max="6442450944"

        Let me know what other information you need.

        Cheers,

        Eric
