I was unable to download as I'm not willing to give dropbox access to my contacts and I'm too lazy to make a new account now. Anyway the culprit is unsupported LPC. Here you go: https://review.coreboot.org/12820

Please send me the full log archive so I can reproduce. Also note: X1 carbon has soldered RAM which will need adjustements

Hi all,


unfortunately autoport didn't work well.


This is the output on the 1st run:

Unsupported PCI device 8086:1e56

Unknown PCI device 8086:0085, assuming removable

panic: runtime error: invalid memory address or nil pointer dereference

[signal 0xb code=0x1 addr=0x20 pc=0x40a157]


goroutine 1 [running]:

main.LenovoEC(0xc20801edc0, 0x19, 0xc20801eec0, 0x1f, 0xc20804638f, 0x6, 0xc20804640a, 0x12, 0xc20803d9e0, 0x2d, ...)

/home/gergap/work/opensource/coreboot/util/autoport/ec_lenovo.go:20 +0x1d37

main.ScanRoot(0xc20801edc0, 0x19, 0xc20801eec0, 0x1f, 0xc20804638f, 0x6, 0xc20804640a, 0x12, 0xc20803d9e0, 0x2d, ...)

/home/gergap/work/opensource/coreboot/util/autoport/root.go:33 +0x52a


/home/gergap/work/opensource/coreboot/util/autoport/main.go:727 +0x683



On further runs the system freezes.

To fix the tree again I run

sudo -R gergap .

git clean -fdx

git reset --hard


This way I could reproduce the above output.


The created log files can be found here:



The created mainboard folder is not really useful,

but if you are interested here is the patch:



Any help is appreciated.
