Also it might be worth trying some different permutations of power applied to the dock before plugging into the machine or after plugging into the machine to see if there is some correlation with a potential ethernet controller bootup race condition. > > For your information, I recompile the kernel and this is the message I > got in /sys/kernel/debug/dynamic_debug/control: > > drivers/net/usb/r8152.c:5149 [r8152]rtl_get_version =_ "Detected version > 0x%04x\012" > drivers/net/usb/r8152.c:1178 [r8152]vendor_mac_passthru_addr_read =_ > "pass-through bit not set.\012" > drivers/net/usb/r8152.c:1170 [r8152]vendor_mac_passthru_addr_read =_ > "Not an AD type.\012" > > Not sure if it is the information you were looking for (sorry, I am new > in kernel debugging). These indicate that you turned on the right dynamic debugging lines, but the actual output of them will show up in your kernel log. If you happen to reproduce the failure again while dynamic debugging is enabled for those it should save to the kernel log what is happening.
