https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252165 --- Comment #17 from Ali Abdallah <ali.abdallah@suse.com> --- After digging further into the code, I'm still unable to understand how the inversion described in comment 14 is even possible... On a spare system T430 with a USB ethernet, I've compiled the kernel with options WITNESS options INVARIANTS options INVARIANT_SUPPORT options DEBUG_LOCKS options DIAGNOSTIC The up/down link issue is even more frequent with the debug kernel, but all I see is if_delmulti_locked: detaching ifnet instance 0xfffff8001880b800 ue0: link state changed to DOWN ue0: link state changed to UP ue0: link state changed to DOWN ue0: link state changed to UP ue0: link state changed to DOWN ue0: link state changed to UP This issue is driving me crazy, any fbsd kernel locking expert to help here? -- You are receiving this mail because: You are the assignee for the bug.
