| mowthegrass | Hi Has anyone faced boot problems with boot screen just hanging with the messaged "random: lvm urandom read with 25 bits of entropy available" | 10:40 |
|---|---|---|
| mowthegrass | Just installed a new kernel apt-get install -y linux-headers-4.4.0-34-generic && apt-get install -y linux-image-4.4.0-34-generic && apt-get install -y linux-image-extra-4.4.0-34-generic | 10:40 |
| mowthegrass | post which system just doesnt boot, Recovery mode doesnt help too | 10:41 |
| mowthegrass | I get the below error in Recovery mode | 10:41 |
| mowthegrass | Gave up waiting for root device. Common problems: | 10:41 |
| mowthegrass | Boot args (cat/proc/cmdline) | 10:41 |
| mowthegrass | check rootdelay = (did the system wait long enough?) | 10:41 |
| mowthegrass | Check root = (did the system wait for the right device?) | 10:41 |
| mowthegrass | Missing modules (cat /proc/modules; ls / dev) | 10:41 |
| mowthegrass | ALERT! /dev/mapper/ubuntu-root does not exist. Dropping to a shell! | 10:41 |
| mowthegrass | However i am able to fall back to the old kernel which was installed prior to 4.4.0.34 | 10:42 |
| apw | mowthegrass, that has not been reportred ... lackof entropy can trigger stalls waiting for new entropy, which could be difficult in early boot | 10:44 |
| apw | if you oculd file a bug against the kernel and indicate the last working version/first broken version you are aware of ... "ubuntu-bug linux" | 10:44 |
| mowthegrass | apw, This doesnt seem to be a BUG whenever we do a new kernel install it throws up with this error , we observed the same while we did 3.19 from 3.16 | 10:46 |
| mowthegrass | not really able to figure this out to be a BUG or something going fishy with the H/W | 10:47 |
| apw | well unless installing hte kernel flushes the saved entropy somehow, i am a little confused | 10:47 |
| apw | have you tried exiting after a few minuted from the initramfs shell to see if by then it is moutnable ? | 10:48 |
| mowthegrass | no no keystrokes are accepted on the console | 10:52 |
| mowthegrass | its just dead with the screen | 10:52 |
| apw | you ought to be able to interact with the initramfs shell so that sounds like a console configuration problem on the kernel command line | 10:53 |
| mowthegrass | I am trying to install linux-image-extra-4.4.0-34-generic to see if anything went missing | 10:55 |
| apw | mowthegrass, is this a virtual machine ? | 10:56 |
| mowthegrass | No | 10:56 |
| mowthegrass | its a DELL R720 | 10:56 |
| apw | you would want -extra installed then, was it not ? | 10:56 |
| mowthegrass | yeah it wasnt installed | 10:59 |
| mowthegrass | just did it now | 10:59 |
| mowthegrass | fingerscrossed | 10:59 |
| mowthegrass | it helped | 11:03 |
| mowthegrass | apw, Thanks for your time | 11:34 |
| mowthegrass | apprecicate it | 11:34 |
| apw | mowthegrass, if you have the right meta package installed it should dpeend on that kernel -extras package | 11:34 |
| apw | to make sure this does not occur again | 11:34 |
| mowthegrass | yep got it | 11:35 |

| manjo | apw, looks like some apparmor stuff landed in unstable .. are you still waiting on more ?or is that the complete list? | 15:12 |
| manjo | jjohansen, ^ | 15:12 |
| apw | manjo, 4.8 in theory is complete | 15:13 |
| manjo | apw, cool thanks | 15:13 |
| manjo | rtg, I see that you guys are active on the Ubuntu-4.8.0-12.13 tag for Y .. if I were to check out a 4.8 tag what would you recommend ? | 17:08 |
| rtg | Ubuntu-4.8.0-12.13 | 17:09 |
| manjo | rtg, thanks | 17:11 |
| manjo | rtg, would you be open to pulling some ACPI related patches from 4.9 next if I made an SRU req ? | 17:13 |
| manjo | rtg, for arm64 | 17:13 |
| rtg | manjo, mail 'em on the k-team list | 17:13 |
| manjo | rtg, yep will do once it is backported and tested | 17:13 |
| rtg | note that 4.9 merge window is still at least 2 weeks away | 17:14 |
| manjo | rtg, are you planning on merging from 4.9 onto Y ? | 17:14 |
| rtg | manjo, nope, 4.8 is the 16.10 kernel | 17:15 |
| manjo | got it | 17:15 |
| manjo | rtg, yeah few critical ACPI patches for arm64 did not make 4.8 and are sitting in 4.9 next.. so will email ukml once it is ready .. you still need an SRU correct ? | 17:16 |
| rtg | manjo, if it is post kernel freeze, which those most assuredly will be | 17:17 |
| manjo | yes that was my feeling for timing as well .. ok thanks a ton | 17:17 |
| _ami_ | is there any document on explanation of hid driver in linux kernel? | 17:20 |
| _ami_ | why few drivers overrides report? e.g. .report_fixup = _override_report; | 17:21 |
| _ami_ | is it because of firmware bugs? | 17:21 |
