| 19:08 | <jgee> I can no longer boot my HP thinclients after upgrading 18.04 (kernel 4.15.0-23 boots ok, but 4.15.0-39 fails). Has anyone had trouble with recent kernels?
| |
| 19:08 | <alkisg> Nope
| |
| 19:08 | Also, really, -23? That's a lot of versions behind
| |
| 19:09 | <jgee> I haven't tested all of the intervening. That's just what I had on a working server
| |
| 19:10 | <alkisg> Are you sure it's the kernel and not some other update or something else?
| |
| 19:10 | What is the error message?
| |
| 19:10 | <jgee> But I don't even update the image. Leaving everything the same, and only changing the pxelinux.cfg/default makes it work or not
| |
| 19:11 | <alkisg> Well then the image doesn't have the modules
| |
| 19:11 | <jgee> No error message, it just fails to boot ("Loading vmlinuz... ok, Loading initrd.img ... ok")
| |
| 19:11 | <alkisg> !quiet-splash
| |
| 19:11 | <ltsp> quiet-splash: to disable the splash screen in Ubuntu, in order to see any boot error messages, run sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and remove quiet splash plymouth:force-splash vt.handoff=7
| |
| 19:12 | <alkisg> Did you run ltsp-update-image after you installed that kernel?
| |
| 19:13 | <jgee> Yes, and it doesn't work. When I change back the kernel in the tftpboot dir, it goes back to working (with or without updating the image)
| |
| 19:15 | <alkisg> Are you using a chroot, or the chrootless setup?
| |
| 19:15 | <jgee> Still chroot
| |
| 19:15 | <alkisg> Did you see any errors while installing that newer kernel?
| |
| 19:16 | <jgee> None
| |
| 19:16 | <alkisg> Do other clients boot?
| |
| 19:17 | <jgee> No, not these old ones (t5740) or newer ones (t630)
| |
| 19:17 | <alkisg> So it doesn't sound like a kernel problem. A new kernel may have issues on some hardware, but it wouldn't make sense if no client booted.
| |
| 19:17 | It sounds like something else
| |
| 19:18 | You could also try with a vm
| |
| 19:18 | !kvm
| |
| 19:18 | <ltsp> kvm: Virtual thin client: kvm -m 256 -vga vmware -ctrl-grab -no-shutdown -net nic,model=virtio -net user,tftp=/var/lib/tftpboot,bootfile=/ltsp/i386/pxelinux.0
| |
| 19:19 | <alkisg> And, do disable "quiet splash" so that you see actual messages
| |
| 19:19 | Finally, make sure that you have the greek schools ppa in the chroot as well, not just on the server
| |
| 19:20 | <jgee> Ok, I'll try that. Thanks!
| |
| 19:20 | <alkisg> np
