Thank you, that is what I suspect but since it worked up until recently, I
thought it would be good to check. I tried to recovery reflash the BIOS
after replacing the battery (I am already at the latest - so no update) no
way to know if it actually did the reflash. Should the e1000e be able to
support the HW configuration in the non-working case (IRQ 20, no MSI, no
bus master)? Because even when lspci reports IRQ 20, e1000e still looks at
46.
Thanks
