https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258057 Bug ID: 258057 Summary: muge(4) crashes with large tx batches Product: Base System Version: CURRENT Hardware: arm64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: dan.kotowski@a9development.com When initiating a large number of flows, the muge(4) driver seems to fall o= ver and the interface flaps until physically removed from and reseated in the U= SB port. I've been able to reliably reproduce this with the following: * freebsd-src/main@9781c28c6d63 * ports/main@58a8a0aa37a8 * poudriere bulk -j $JAIL -p $PORTS devel/gh The devel/gh port seems to initiate a large number of outbound TCP sessions, which seem to trash the TX queue to the point of making the interface unusa= ble. * dmesg flooded with `ue0: link state changed to DOWN|UP` * ping returns "sendto: No buffer space available" until exit Hardware: https://bsd-hardware.info/?probe=3D8a7b477512 --=20 You are receiving this mail because: You are the assignee for the bug.=
