https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=212413 freebsd@mcwest.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |freebsd@mcwest.org --- Comment #3 from freebsd@mcwest.org --- (In reply to nicolas from comment #2) FYI, including ALTQ in the kernel config switches igb(4) interfaces to legacy single-queue mode. I have seen crashes like these with high-bandwidth traffic when the driver is in this mode. If you need ALTQ, add a queue to limit throughput through igb interfaces. For example, the following workaround has prevented crashes on my systems for the last six months: ## Limit bandwidth on internal interface to avoid igb driver bug altq on $int_if cbq bandwidth 404Mb queue { internal } queue internal bandwidth 99% priority 1 cbq(default red borrow) -- You are receiving this mail because: You are the assignee for the bug.help
