Sometimes, when booting one of my apu2 systems with two of the WLE900VX
NICs in it, one of them does not show up in lspci.
this is a well known bug. but its a bug in the apu
i was talking about such issues with pcengines already but so solution
yet.
Here is the pertinent (I think) bit of dmesg:

Rebooting the system usually 'fixes' the problem, but sometimes it
takes several reboots.
Does this provide any clues?
Any suggested work-arounds I could try?
Thanks,
