trippehHm. Something something module autoloading during initramfs seems to be borked with kernel 3.16-git (upstream)17:30
trippehOn 14.0417:30
apwtrippeh, any specific module?17:38
trippehahci.ko didnt get loaded, but loads fine on modprobe after dropping to initramfs-shell. I still cant get it to finish boot though, seems like something related to dm-crypt is failing too.17:40
trippehso I'm guessing something is just rong with autoloading in general17:41
trippeh3.15.4-rc with similar config works fine.17:42
trippehHm. udev is supposed to start during initramfs right?21:50
trippehhmm. starts ok if I start it manually within the initramfs shell21:58
trippehodd.21:58
trippehudev didnt start by itself, but only with 3.1622:01
trippehonto something22:14
trippehoh. /sys/kernel/uevent_helper seems to be gone, making the udev initramfs script fail before starting udev.22:16
trippeh-CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug"22:17
trippeh+# CONFIG_UEVENT_HELPER is not set22:17
trippehheh :)22:17
trippehsilly me22:18
trippehkernel says "should not be used today"22:19
trippehI'm thinking maybe the echo > /sys/kernel/uevent_helper is a relic of the past22:21
trippehudev started and worked fine without it.22:22
trippehah yes. the echo is to disable it.22:24
trippehbut when disabled in the kernel build anyway, it doesnt exist anymore.22:25
trippehso I guess it should have a if it exists, then try disabling it.22:25
* trippeh rambles on22:26
trippehwrapped it in a if and now it boots cleanly22:29
phillwscary things, these kernels!22:37
trippehwill re-enable the legacy kernel option and file a minor bug on initramfs-tools22:40
phillwtrippeh: are we sticking with 3.15 for 14.10 release?22:42
trippehnot sure, I'm just an observer who breaks things :)22:43
phillwtrippeh: ahh, I'm similar... I have a non-pae 3.13 kernel which I've added the aufs patches to :)22:45
trippeherr, its udev that should get the bug22:47
trippeh$ dpkg -S /usr/share/initramfs-tools/scripts/init-top/udev 22:47
trippehudev: /usr/share/initramfs-tools/scripts/init-top/udev22:47
trippehprobably not worth fixing in 12.04/14.04, as its a non-ubuntu-standard configuration22:48
