https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211713 Wolf Noble <freebsd@wolfspaw.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |freebsd@wolfspaw.com --- Comment #69 from Wolf Noble <freebsd@wolfspaw.com> --- I can confirm this bug rears it head on a dell r510 running freenas11.2 (which follows freebsd11.2) if I use a synology m2d18 https://www.synology.com/en-us/products/M2D18 dual NVME pci card. I cannot get diskinfo to run cleanly without the target going to lunch. Setting hw.nvme.enable_aborts=1 via a loader.conf tunable (and rebooting) had no impact in my case. disabling or enabling hyperthreading does not seem to impact this hang, although having hyperthreading enabled seems to prevent MSIX from being used. if I take the nvme devices out of the synology dual card and put them into a single nvme->pci adapter, I do not (yet) seem to have the problem. happy to provide whatever details might be useful in making progress, but figured that just the additional info might be sufficiently useful without superfluous noise. -- You are receiving this mail because: You are the assignee for the bug.help
