https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258057 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 over and the interface flaps until physically removed from and reseated in the USB 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 unusable. * 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=8a7b477512 -- You are receiving this mail because: You are the assignee for the bug.home | help
