The resulting kernel boots, but while starting some jails (with ezjail from ports, so fairly late in the boot process) I get a kernel panic (IIRC zfs trying to access page 0). Before I try to get some time to debug this, I would like to know if there are some known incompatibilities with my make.conf settings. With gcc I used successfully this: ---snip--- COPTFLAGS= -O2 -pipe CPUTYPE?=core2 ---snip--- With those settings I first did a buildworld, then a buildkernel with the r251618 sources. Are there some known issues with those settings? If yes, any suggestions what I should use instead? If not, would it be beneficial to try with different settings (which ones)?
