Question Problems booting Debian 9.5 on ThinkPad X260


I recently bought my first PC laptop (a Thinkpad x260) and installed Debian 9.5 stable onto it. It seems that it won't boot unless I pass either the nolapic or acpi=off flags in grub when booting. If I do that the system boots, but it only recognizes one core of the CPU. Does anyone have any ideas what it could be?

I've updated my bios to the latest version have am also upgraded the kernel to 4.18.0 from the stretch-backports repository, but the problem is still there.

Does it work when you add both noapic and acpi=off in grub?

PS: you'll also need non-free firmware for your wifi on x260 (firmware-iwlwifi)

Yes, it boots as usual when adding both those flags but /proc/cpuinfo still only shows one core available.

Yes, I've installed that and my wifi is working but I'm getting some errors in dmesg.

Try acpi=ht. This is the next most stringent spec after "acpi=off". It allows hyperthreading between processors but nothing else.

It did not help. Got a crash immediately after grub. It only printed out something like "[0.00081] kernel" and then hangs. :/

It turns out I got the wrong laptop from the person I bought it from (he had two and got them mixed up) so I ended up returning the one with this error and got new one. The new laptop does not have these issues so it was probably something funky going on with the hardware (my guess would be motherboard / cpu).

So to the future person who reads this - I'm sorry I couldn't help but you might want to look into faulty hardware.
