https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211620 Bug ID: 211620 Summary: Cannot boot on zfs with nvme in system Product: Base System Version: 10.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: braddeicide@hotmail.com As soon as I plug an nvme into my system I can't boot on zfs root (ZFS enabled bootstrap loader). I can load from DVD, and I've since reinstalled onto a temporary UFS root system and everything works fine. The system freezes during the BTX loader screen, the drive is given a BIOS drive letter, then the spinner stops before the "Bios 625kB/3654644kB available memory" screen. Some grepping brings me to this loop https://svnweb.freebsd.org/base/release/10.3.0/sys/boot/i386/loader/main.c?revision=297553&view=markup#l172 Zfs appears to have its own dv_init here: https://svnweb.freebsd.org/base/release/10.3.0/sys/boot/zfs/zfs.c?revision=297553&view=markup#l385 >From this point I hope someone might have a better idea than printf debugging :) The nvme is a Samsung 950 pro, it's in a pcie m2 card. I can dig out exact model of mount if required. #nvmecontrol devlist nvme0: Samsung SSD 950 PRO 512GB nvme0ns1 (488386MB) # diskinfo -v /dev/nvd0 /dev/nvd0 512 # sectorsize 512110190592 # mediasize in bytes (477G) 1000215216 # mediasize in sectors 512 # stripesize 0 # stripeoffset S2GMNCAGA01093W # Disk ident. # pciconf -lv | grep nvme -A3 nvme0@pci0:3:0:0: class=0x010802 card=0xa801144d chip=0xa802144d rev=0x01 hdr=0x00 vendor = 'Samsung Electronics Co Ltd' class = mass storage subclass = NVM re severity, I came across someone else with exact same problem on forums. -- You are receiving this mail because: You are the assignee for the bug.help
