Downstream bug, Fedora Rawhide being a canary in the coal mine! https://bugzilla.redhat.com/show_bug.cgi?id=1575797 Comment 8 about the kernel warning related to freeze/thaw is curious but ends up being unrelated to this problem. The gist is that xfsprogs 4.16.0 formatted volumes aren't recognized by either GRUB user space tools, or the GRUB core.img (whether of the embedded BIOS variety or the grubx64.efi variety) Anyway, open question for XFS devs if this should be fixed in xfsprogs or GRUB. I haven't tested this with syslinux to know if it has a similar problem. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
