ACB: 35 00 50 29 10 40 6c 00 0c 00 (ada0:ata2:0:0:0): CAM status: Command timeout (ada0:ata2:0:0:0): Retrying command for all 6 sata hdd(mirror from 2 raidz) Hardware: Supermicro X8DTN+-F / 6xWD1502FYPS-02W3B0 /2xE5649 HDDs connected to sata ports on baseboard. If I add=20 hint.ata.2.mode=3DPIO4 hint.ata.3.mode=3DPIO4 hint.ata.4.mode=3DPIO4 hint.ata.5.mode=3DPIO4 to device.hints I'm able to boot but performance of IO becomes really disappointing. If I roll back system to 11.0 all works fine again. What was done so far: 1) Placed disks with same sata cables to another PC - boots fine 2)Tried separate raid controller on this baseboard - doesn't boots properly 4)Used separate power supply for disk - the same errors. 5)Used another power supply for whole system - no effect, same issue Also, if I add to /etc/rc.d/zfs something like=20 "find / -name something" after "zfs mount -a" it boots too(without modifica= tion of device.hints), but after some time igb0(there is torrent traffic on it)w= ill hung and only reboot helps, maybe this is related or this is some separate = bug. I don't remember exact dmeseg message for hung of igb0, but will post update when will face it again. --=20 You are receiving this mail because: You are the assignee for the bug.=
