I won't swear that all of the problems I'm seeing are 100% kdbus' fault, but Rawhide, updated today, has serious problems with the kdbus branch in Greg's char-misc tree. Problem 1: Booting a kdbus-enabled kernel (CONFIG_KDBUS=y) causes gdm to bail saying "oops, something went wrong" or whatever the useless standard error message is. I can work around problem 1 by booting with kdbus=1, but that's not okay. Unless this is limited to just some narrow range of Rawhide versions, I don't think the kernel gets to make changes that break userspace like that. Maybe this is a kernel issue, not a user issue, in which case it's not a big deal as long as it gets fixed. Problem 2: Running 'sudo mount /mnt/share' from a terminal hangs the whole graphical session hard. This is repeatable. /mnt/share is virtfs, but I doubt that matters. If I build exactly the same sources but set CONFIG_KDBUS=n, all is well. I suspect that there are multiple issues here: 1. The current state of systemd's --disable-kdbus could be buggy. kdbusfs still gets mounted but isn't set up and then things break. 2. mount generates a bunch of dbus traffic. Apparently on the latest char-misc kdbus tree with the latest Rawhide, it blows up somehow. That's all from me until next week. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
