Same dmesg output and crash profile, same achi controller : # uname -a FreeBSD Daguerreo 10.1-RELEASE FreeBSD 10.1-RELEASE #0 r274401: Tue Nov 11 21:02:49 UTC 2014 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 #pciconf -vl [...] ahci0@pci0:0:17:0: class=0x010601 card=0x1609103c chip=0x43911002 rev=0x40 hdr=0x00 vendor = 'Advanced Micro Devices [AMD] nee ATI' device = 'SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode]' class = mass storage subclass = SATA [...] I was able to reduce the mean time between crashes by slowing down the sata links to 1.5 Gb/s (by adding `set hint.ahcich.[0..4].sata_rev=1` to /boot/loader.rc.local). It still crashes when scrubbing my zpool, but it will do so much farther. -- You are receiving this mail because: You are the assignee for the bug.
