While trying to move my computer to Debian, after allowing the installer to do it’s task, my machine will not boot.
Instead, I get a long string of text, as follows:
Could not retrieve perf counters (-19)

And the system eventually collapses into a shell, that I do not know how to use. It returns:
Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait lomg enough?)
- Missing modules (cat /proc/modules; ls /dev)
Alert! /dev/sdb2 does not exist. Dropping to a shell!
The system has two disks mounted:
– an SSD, with the EFI, root, var, tmp and swap partition, for speeding up the overall system – an hdd, for /home
I had the system running on Mint until recently, so I know the system is sound, unless the SSD stopped working but then it is reasonable to expect it would no accept partitioning. Under Debian, it booted once and then stopped booting all together.
The installation I made was from a daily image, as I am/was aiming to put my machine on the testing branch, in order to have some sort of a rolling distro.
If anyone can offer some advice, it would be very much appreciated.


Debian is well known for its stability but it is also known for being tricky to handle when moving into the Testing branch and I did just that, by wanting to have a somewhat rolling distro with Debian.
I’m no power user. I know how to install my computer (which is a good deal more than most people), do some configurations and tinker a bit but situations like this throw me into uncharted territory. I’m willing to learn but it is tempting to just drop everything and go back to a more automated distro, I’ll admit.
Debian is not to blame here. Nor Linux. Nor anyone. We’re talking about free software in all the understandings of the word. Somewhere, somehow, an error is bound to happen. Something will fail, break or go wrong.
At least in Linux we know we can ask for help and eventually someone will lend a pointer, like here.
OpenSuse Tumbleweed is a great balance between stable and updates (rolling updates). Worth considering if Debian doesn’t work out.
I’m a sucker for Debian. It was my first good and reliable workhorse. First love is hard to forget.
