[qubes-users] LG Gram 17" (2021) - reboots before I can see any error messages

Having trouble even booting on LG Gram 17" (2021) laptop - suspect a hardware/driver issue but the system reboots before I can read anything… Any ideas how I can troubleshoot this?

Many thanks!

Check the docs here, in particular install & UEFI: Documentation | Qubes OS.

Thanks! I managed to identify it’s a problem with APIC and/or timer… But noapic doesn’t seem to help - just get a reboot at some point during the kernel init…

Tried the 4.1 alpha, same problem with Xen?

Could be, Xen is often a bit behind the curve when it comes to leading edge hardware. If it has an nvidia card, did you see the related document? Last thing to try (but you probably have already) is to search this mailing list and forum and HCL for other LG notebooks to see if they encountered a similar problem and figured it out. Sorry, only have generic advice on this one.
