I've bisected the kernel regression and tracked it to r297857: https://svnweb.freebsd.org/base?view=3Drevision&revision=3D297857 I've also attached a patch that "fixes" the regression. I'm sure this isn't= the proper fix, but at least now I can upgrade from FreeBSD 10.3. With this patch, the 10.4 kernel now boots just fine (it did not before). I= am currently building the 11.1 release from source with this patch and will re= port back when done. --=20 You are receiving this mail because: You are the assignee for the bug.=
