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
main.main()
        /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.
