https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #39 from Roger Pau Monn=C3=83=C2=A9 <royger@freebsd.org> --- (In reply to rainer from comment #36) There's clearly something wrong there, you are not receiving as many interr= upts as you should be, this is what I usually see when running dc3dd: irq808: xen_et0:c0 17545 93 irq809: xen_et0:c1 73460 391 irq810: xen_et0:c2 65527 349 irq811: xen_et0:c3 73980 394 irq814: xbd1 314436 1674 (note that xbd1 is the disk against which the dc3dd is run) In your case this is: irq768: xen_et0:c0 4061306 20 irq769: xen_et0:c1 1951430 10 irq773: xbd0 1652038 8 irq774: xbd1 29 0 irq775: xbd2 159503 1 Note the difference in the rate of interrupts (from 1674 in my case). Can you also post the results of running `sysctl -a | grep xbd` inside the FreeBSD guest? Thanks! --=20 You are receiving this mail because: You are the assignee for the bug.=
