Ubuntu can be started and runs without problems with Linux kernel 4.4.0-45. When I try to start with any of the 4.8.0 kernels delivered with regular Ubuntu updates, they all hang after printing Läser in Linux 4.8.0-34-generic ... Läser in initial ramdisk ... Sorry for the partly Swedish text. I guess that the lines would start with "Loading" instead of "Läser in" on an English version. The behaviour is the same with all 4.8.0 versions up to the latest 4.8.0-34 and with -generic, -generic (upstart) and -generic (recovery mode). After a while the fan runs at full speed, as if the processor is working hard, but nothing happens. After I've tried in vain to start with Linux 4.8.0-xx, and then starts with 4.4.0-45, the following errors are usually printed: [ 2.511733] usb 4-3: string descriptor 0 read error: -22 [ 3.841872] [drm:radeon_scpi_init [radeon]] *ERROR* Cannot find backlight controller /dev/sda7: clean, 807007/9363456 files, 7364300/37423360 blocks [ 21.335117] usb 4-3: string descriptor 0 read error: -22 When a successful start has not been immediately preceded by a failed start, only the line beginning "/dev/sda7" is printed. I have previously commented on bug #1635447. As recommended there, I've also tested with the upstream kernel 4.10-rc3. It worked just as bad as 4.8.0. I tried to report this bug with 'ubuntu-bug linux' after I had booted with the 4.4.0-45 kernel, but I couldn't. It said that linux-image-4.4.0-45- generic is not an official Ubuntu package. --- ApportVersion: 2.20.3-0ubuntu8.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: kjell 2022 F.... pulseaudio /dev/snd/controlC1: kjell 2022 F.... pulseaudio /dev/snd/controlC0: kjell 2022 F.... pulseaudio CurrentDesktop: GNOME-Flashback:Unity DistroRelease: Ubuntu 16.10 HibernationDevice: RESUME=UUID=d42f8b71-8244-45d9-a814-ca7b9fb474bb InstallationDate: Installed on 2013-09-25 (1218 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: Acer Aspire V5-551G Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-45-generic.efi.signed root=UUID=b953dea5-2c7a-4d65-9b8e-446b111ccce8 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 4.4.0-45.66-generic 4.4.21 RelatedPackageVersions: linux-restricted-modules-4.4.0-45-generic N/A linux-backports-modules-4.4.0-45-generic N/A linux-firmware 1.161.1 Tags: yakkety Uname: Linux 4.4.0-45-generic x86_64 UpgradeStatus: Upgraded to yakkety on 2016-10-26 (91 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 03/11/2013 dmi.bios.vendor: Insyde Corp. dmi.bios.version: V2.14 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: Havok dmi.board.vendor: Acer dmi.board.version: Type2 - A01 Board Version dmi.chassis.type: 10 dmi.chassis.vendor: Chassis Manufacturer dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsydeCorp.:bvrV2.14:bd03/11/2013:svnAcer:pnAspireV5-551G:pvrV2.14:rvnAcer:rnHavok:rvrType2-A01BoardVersion:cvnChassisManufacturer:ct10:cvrChassisVersion: dmi.product.name: Aspire V5-551G dmi.product.version: V2.14 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1659340/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
