This happens both when doing portsnap extract and clone from git repository= . For example portsnap extract, the extraction process (the output of it) suddenly stops, for seconds or maybe even minutes, quite many times during the whole extraction process. iostat reports ~200 MB/s on ada0 the whole time during freeze. pciconf: ahci0@pci0:4:0:0: class=3D0x010601 card=3D0x91831b4b chip=3D0x91831b4b rev=3D0x14 hdr=3D0x00 vendor =3D 'Marvell Technology Group Ltd.' class =3D mass storage subclass =3D SATA dmesg (relevant lines?): ahci0: port 0x1028-0x102f,0x1034-0x1037,0x1020-0x1027,0x1030-0x1033,0x1000-0x101f mem 0xb0700000-0xb07001ff at device 0.0 on pci4 ahci0: AHCI v1.00 with 1 6Gbps ports, Port Multiplier not supported ahcich0: at channel 0 on ahci0 ada0 at ahcich0 bus 0 scbus0 target 0 lun 0 ada0: ATA-8 SATA 3.x device ada0: Serial Number 1325A5401681 \^T\^T\^T\^T\^T\^T\^T ada0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 512bytes) ada0: Command Queueing enabled ada0: 115712MB (236978176 512 byte sectors: 16H 63S/T 16383C) ada0: Previously was known as ad4 GEOM: ada0: enabling Boot Camp GEOM: diskid/DISK-1325A5401681%20%14%14%14%14%14%14%14: enabling Boot Camp gpart: =3D> 34 236978109 ada0 GPT (113G) 34 6 - free - (3.0K) 40 409600 1 efi (200M) 409640 174519128 2 apple-hfs (83G) 174928768 1269536 3 apple-boot (620M) 176198304 1376 - free - (688K) 176199680 29782016 4 linux-data (14G) 205981696 2097152 5 linux-swap (1.0G) 208078848 1600 6 efi (800K) 208080448 27261368 7 freebsd-ufs (13G) 235341816 1445888 8 freebsd-swap (706M) 236787704 190439 - free - (93M) One other weird thing is that FreeBSD does not show up in the refind boot menu by default, only OSX and Linux. I have to press ESC once to reload for FreeBSD boot option to show up.. Any clues? Is my partition configuration wrong in some way?
