marja11 I have not dared to set up a system with /boot encrypted... yet :) Did you achieve this using the mageia installer? Do you have grub2 loading the encryption module? FWIW Bug 18495 *may* me related: i have en encrypted LVM for everything except /boot, set up and worked OK in mga5, but after updating to cauldron it can not be unlocked in text mode boot, only graphical...

fri (In reply to Morgan Leijström from comment #1) > I have not dared to set up a system with /boot encrypted... yet :) > Did you achieve this using the mageia installer? Yes, using Mageia installer. It worked fine until 4.6. > Do you have grub2 loading the encryption module? I think, it should be or how it worked before? I haven't seen any encryption-related errors, it just hangs with no output. > FWIW Bug 18495 *may* me related: i have en encrypted LVM for everything > except /boot, set up and worked OK in mga5 No, this is a duplicate of another bug report that I opened :) That's a different problem and a workaround exists. I can't use separate /boot because I use btrfs + snapshots for root partition. It's still not fixed and should be a release blocker, as the only kernel that works is 4.4. Mass-reassigning all bugs with "kernel" in the Source RPM field that are assigned to tmb, to the kernel packagers group, because tmb is currently MIA. Assignee:

tmb Nothing changed. Seems, it doesn't even leave the grub (I see a black rectangle over the grub menu). Created attachment 8443 [details]
grug config
Attached grub config
(In reply to Nikita Krupenko from comment #8) > Created attachment 8443 [details] > grug config > > Attached grub config Some questions: 1. Does it still happen with the 4.7.4-2mga6 kernel? 2. Does it happen with a recent vanilla kernel from www.kernel.org (such as our kernel-linus)? If so, then you should report this problem to the upstream Linux kernel devs CC:

shlomif Still happens with the recent kernel and kernel-linus. Are you sure, that it's a kernel bug and not a bug in way, the kernel is installed? I reported similar problem recently, see bug 18112 I tried several other distros. OpenSUSe with kernel 4.4 seems to work, but Fedora and Kubuntu with kernel 4.8 doesn't. Seems it really could be an upstream bug. So what to do now? Opened bug in the kernel's bug tracker. URL:

https://bugzilla.kernel.org/show_bug.cgi?id=189241 Some things to test to try and figure out where it fails... try without encryption try encryption with separate unencrypted boot try without btrfs (use ext4 instead) As I wrote in the previous comment, other distros with the recent kernel doesn't even start from usb, so I don't think, that encrypted partitions on a hard disk can somehow affect this. With kernel 4.9.9 and later I can't reproduce this bug. Status:
