Hi, I am just having trouble with my opensolaris in a virtual box. It refuses to boot with the following crash dump: panic[cpu0]/thread=d5a3edc0: assertion failed: 0 =dmu_buf_hold_array(os, object, offset, size, FALSE, FTAG, &numbufs, &dbp), file: ../../common/fs/zfs/dmu.c, line: 614 d5a3eb08 genunix:assfail+5a (f9ce09da4, f9ce0a9c) d5a3eb68 zfs:dmu_write+1a0 (d55af620, 57, 0, ba) d5a3ec08 zfs:space_map_sync+304 (d5f13ed4, 1, d5f13c) d5a3ec7b zfs:metaslab_sync+284 (d5f1ecc0, 122f3, 0,) d5a3ecb8 zfs:vdev_sync+c6 (d579d940, 122f3,0) d5a3ed28 zfs:spa_sync+3d0 (d579c980, 122f3,0,) d5a3eda8 zfs:txg_sync_thread+308 (d55045c0, 0) d5a3edb8 unix:thread_start+8 () This is on snv_117 32-bit Is this a known issue? Any workarounds? - Thomas
