While trying to reproduce by unplugging/replugging ethernet and resuming/suspending a lot I found the following in dmesg after one of the resumes - the system seems to be working fine though and network works as well, so it's not the same complete crash but it looks potentially related : [ 6564.921192] e1000e 0000:00:19.0: restoring config space at offset 0x1 (was 0x100103, writing 0x100107) [ 6564.921222] ehci_hcd 0000:00:1a.0: restoring config space at offset 0xf (was 0x400, writing 0x40b) [ 6564.921240] ehci_hcd 0000:00:1a.0: restoring config space at offset 0x4 (was 0x0, writing 0xf2828000) [ 6564.921247] ehci_hcd 0000:00:1a.0: restoring config space at offset 0x1 (was 0x2900000, writing 0x2900102) [ 6564.937545] ehci_hcd 0000:00:1a.0: power state changed by ACPI to D0 [ 6564.937554] ehci_hcd 0000:00:1a.0: power state changed by ACPI to D0 [ 6564.937708] pcieport 0000:00:1c.1: restoring config space at offset 0x7 (was 0xf0, writing 0x200000f0) [ 6564.937805] pcieport 0000:00:1c.4: restoring config space at offset 0xf (was 0x100, writing 0x4010b) [ 6564.937815] pcieport 0000:00:1c.4: restoring config space at offset 0x9 (was 0x10001, writing 0x1fff1) [ 6564.937820] pcieport 0000:00:1c.4: restoring config space at offset 0x8 (was 0x0, writing 0xf250f250) [ 6564.937824] pcieport 0000:00:1c.4: restoring config space at offset 0x7 (was 0x20000000, writing 0x200000f0) [ 6564.937832] pcieport 0000:00:1c.4: restoring config space at offset 0x3 (was 0x810000, writing 0x810010) [ 6564.937838] pcieport 0000:00:1c.4: restoring config space at offset 0x1 (was 0x100000, writing 0x100107) [ 6564.937872] ehci_hcd 0000:00:1d.0: restoring config space at offset 0xf (was 0x400, writing 0x40b) [ 6564.937890] ehci_hcd 0000:00:1d.0: restoring config space at offset 0x4 (was 0x0, writing 0xf2828400) [ 6564.937897] ehci_hcd 0000:00:1d.0: restoring config space at offset 0x1 (was 0x2900000, writing 0x2900102) [ 6564.937915] ehci_hcd 0000:00:1d.0: power state changed by ACPI to D0 [ 6564.937918] ehci_hcd 0000:00:1d.0: power state changed by ACPI to D0 [ 6564.938019] ahci 0000:00:1f.2: restoring config space at offset 0x1 (was 0x2b00007, writing 0x2b00407) [ 6564.938085] intel ips 0000:00:1f.6: restoring config space at offset 0xf (was 0x400, writing 0x40b) [ 6564.938107] intel ips 0000:00:1f.6: restoring config space at offset 0x1 (was 0x100000, writing 0x100002) [ 6564.938674] PM: early resume of devices complete after 17.784 msecs[ 6564.939048] sdhci-pci 0000:0d:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 6564.939053] iwlagn 0000:03:00.0: RF_KILL bit toggled to disable radio.
