Hi Alexander, Thanks
On the first time, I did see following error: d0(pciide0:0:0): timeout type: ata c_bcount: 512 c_skip: 0 pciide0:0:0: bus-master DMA error: missing interrupt, status=0x21 But it went away once booted and no longer appeared, unless I mirrored my HDD again and boot from the same board. Plain keyboard and monitor, no serial console plugged in. I did try to config wd0 with flags 0xfac or 0xffc without luck: above error disappeared but still stopped on boot> Please see bellow for dmesg, which was generated once hit Return key to continue boot sequence from boot>.
