Lenovo Thinkpad x240
I can try to help out, but I’ll need to know more about the chip the ethernet card is using.
Are you sure its stuck? Or just taking a long time. acpi_namespace_walk is a typical “error” that really doesn’t mean anything.
I have HP Laptops, that seemingly, take 3 minutes before they actually start to do anything. This is with my current kernel.
That’s not to say this is the case here, but I’ve watched guys where I work start banging their heads thinking somethings was broke, when they just weren’t waiting long enough.
I’ll look up more about the Thinkpad x240 to see if I can find out more specifics about the network driver but it seems to me it may just be a chipset driver that’s missing, rather than a network or hard drive driver that’s missing.
I’ll try looking around a little bit.
