The trace says it is falling back to legacy interrupts, does the system continue to work and does the network continue to function in that mode? In case it's related to user space what is the base distro? Any other information you think can help me reproduce the issue would be appreciated. > Config attached, the machine is a Thinkpad X61s 1.8Ghz with no onboard wireless devices (rtl8192cu usb wifi is used). # lspci| grep -i eth 00:19.0 Ethernet controller: Intel Corporation 82566MM Gigabit Network Connection (rev 03) Debian jessie amd64 is the distro. I'll have to get back to you on if the e1000e continues functioning, the machine continues to function until the shutdown panic. There were however some occurrences of subsequent suspend/resume cycles hanging the machine hard leaving the display off, which prompted me to resume using 4.10 before digging any further as it's my only system right now. Will try get around to testing 4.11 with 7e54d9d063fa reverted soon. Regards, Vito Caputo
