You should always unmount the mount point before fsck'ing any filesystem. Kind regards, Andrey Arapov If your boot partition needs fsck'ing after something writes to it (like a Qubes update), then it seems that the partition needs to be fixed.

Re: [qubes-users] No boot after dom0 kernel update
I want to make clear that in each case, the new kernel has worked fine once I persuaded my BIOS to boot it.

I am far from certain that the fsck.vfat was what restored bootability, but something did. dom0 kernel upgrade should not leave the boot partition in such undesired state, unless there is some hard to reproduce bug. Otherwise it will get fixed really soon. I do not have whole lot of details about your configuration.. but if you really believe this issue is caused by the dom0 kernel upgrade script, then try to reproduce it in a minimal amount of steps, e.g.: 1. install qubes os of version X.Y.Z with the /boot on FAT FS (+ any other custom settings you have, including if you have a dual boot); 2. run qubes-dom0-update kernel-x.y.z; Otherwise it's hard to help. You can also inspect the install scripts by yourself: $ rpm -q --scripts kernel $ less /bin/kernel-install Kind regards, Andrey Arapov -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Is there a way to get reliable booting after a dom0 kernel update? I am afraid that there is no such way as the new Linux kernel adds new features, changes the current ones, which are unlikely were thoroughly tested (or if tested at all) for the whole range of HW out there or their combinations.

[qubes-users] No boot after dom0 kernel update
I find that, when I update dom0 with a new kernel, too often my machine won't boot anymore, after the update. Then I need to tinker with the boot partition. It seems as if, this last time, what worked was to run fsck.vfat on the partition. I am (I hope understandably) reluctant to mess about with this bit of infrastructure without strong need. The machine is an ASUS K501UW, UEFI boot only, that needs "nouveau.modeset=0" to avoid frequent kernel oopses, so installing was a chore. Is there a way to get reliable booting after a dom0 kernel update? Do I need to unmount my /boot partition and fsck.vfat it before rebooting? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
