Dear Andriy and FreeBSD community, With patch system panic on boot. After remove cache device from pool system boot without problem. After this cache added again and sone kernel panic happened Screen shot of panic here http://i61.tinypic.com/30sbx2g.jpg Vitalij Satanivskij wrote: VS> Dear Andriy and FreeBSD community, VS> VS> Build world with path failed with error VS> VS> /usr/src/cddl/lib/libzpool/../../../sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c:4642:13: error: use of VS> undeclared identifier 'l2hdr' VS> ASSERT3P(l2hdr->b_tmp_cdata, ==, NULL); VS> ^ VS> /usr/src/cddl/lib/libzpool/../../../sys/cddl/contrib/opensolaris/uts/common/sys/debug.h:125:40: note: expanded from VS> macro 'ASSERT3P' VS> #define ASSERT3P(x, y, z) VERIFY3_IMPL(x, y, z, uintptr_t) VS> ^ VS> /usr/src/cddl/lib/libzpool/../../../sys/cddl/contrib/opensolaris/uts/common/sys/debug.h:109:29: note: expanded from VS> macro 'VERIFY3_IMPL' VS> const TYPE __left = (TYPE)(LEFT); \ VS> ^ VS> 1 error generated.
