Unable to boot: Rebuild hardware database

Hi

Since this morning, one of my computer is not booting anymore. The first lines are changing from:
- A start job is running for dev-disk-by ...
- A start job is running for Rebuild Hardware Database

I then get error messages telling:

ata2.00: exception Emask 0x0 SAct 0x300000 SErr 0x0 action 0x6 frozen
ata2.00: failed command: READ FPDMA QUEUED
ata2.00: cmd <...> tag 20 ncq dma 12288 in
              res <...> EMask 0x4 (timeout)
ata2.00: status: ( DRDY )
...

I get similar message for all the partitions (/dev/sda1, /dev/sda3, /dev/sdb1)

When I let the jobs complete, I get this message:

[ TIME ] Timed out waiting for device dev-disk-by... device
[DEPEND] Dependency failed for /boot/efi
[DEPEND] Dependency failed for local system
[DEPEND] Dependency failed for File System Check on ... 

Similar message for all partitions: /boot/efi, Swap, /docs (/ not directly printed)

It continues a bit with Started Emergency Shell but it stops with more errors before I get a root shell.

I tried to boot on an arch-linux USB and did not get any problem. I was able to mount all the disks and access them, chroot, try a pacman update (but the system is up-to-date).

I ran fsck on each of the partitions. Except /dev/sda1 (/boot/efi) which was dirty, it did not find errors.

Any idea what I should try now?

Edit: I launched an Ubuntu live disk; It starts normally, I can mount the disks and access them. This does not look like an hardware problem.

Re: Unable to boot: Rebuild hardware database

Can you still boot the failsafe initramfs?

No I tried to boot in fail-safe mode and it did not help. I also have linux and linux-lts, and same problem for both.

Re: Unable to boot: Rebuild hardware database

Do you have a paralell windows installation? Is it either hibernated or did you forget to disable windows fastboot (which essentially is hibernation)?

Re: Unable to boot: Rebuild hardware database

No this is a pure Linux, no dual boot, and Windows has never been installed on it. I have been using arch-linux for 2 years on this machine now.

What does it have to do with windows parallel installation?

Re: Unable to boot: Rebuild hardware database

It's more about a hibernating windows (or actually any hibernating OS) leaving the HW in an undefined state. Since it's not the kernel (version) nor the HW outside the boot context, something lingering around on the bus, causing random havoc was my last best guess.

Please be re-informed to not necro-bump, esp. not w/ personal curiosity about established dead ends (aka "empty posts"), see the NC stickies.

Re: Unable to boot: Rebuild hardware database

This was actually due to a failing SSD disk (Confirmed with the vendor)
