Looking at bugs on lvm2 turns up this gem in bug #802626: > Just a wild speculation, because I haven't yet digged into the interactions > between kernel > and udevd, but the semaphore decrementation event might be lost when > transitioning from > the initrd-udevd to the rootfs-udevd.
In cases where people are seeing initrd problems and lvm is in use, are there always LVM VGs *other* than for the root fs? If there's a VG that's not a dependency of the rootfs, then indeed the vgchange call can be racing the main initramfs sequence. Twiddling the lvm2 package to insert a delay may help with reproducing the issue. None of this explains any issues with device nodes being absent from /dev on the root filesystem when lvm is *not* in use. The original bug report did not mention LVM at all. Can someone comment on the disk configuration used there? Maybe we need to split this into two bugs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/818177 Title: boot failures caused by udev race To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/818177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
