The "system timer" setting should indeed do the check and it does
not. I will add the check to that part of the code to avoid misleading
users.
It is odd that Debian would not offer a 1000Hz kernel. Ubuntu's
default kernel is now real-time and 1000Hz. Debian must offer
something. Check the kernel packages.
Worst-case you'll have to build your own. Fortunately that's easier
than it sounds. My (slightly outdated) instructions are here if you
need them:

So... It was already set to "auto". Then, I changed to "system

perhaps the "auto" setting is not working as expected?
Actually, it looks like the "system timer" setting does not perform
the resolution checks. Can you try the following on your system:
$ grep ^CONFIG_HZ /boot/config-`uname -r`
Oh, I see. You mean this:
CONFIG_HZ_250=y
CONFIG_HZ=250
It seems then that Debian ships a kernel patched for real-time, that
operates at 250Hz (?)
But shouldn't the "system timer" setting actually do check if the timer
is good?
