Just a note for anybody who might have this problem with 9.2 that I am still having this issue with 9.2-releng (unless I patch the kernel) and Andriy hasn't accessed my system yet, to have a look so 9.2 release is likely to have this same issue for some subset of users (maybe only 1, me!). We were able to figure out that my symptoms have nothing to do with the user of powerd (still happens if powerd is not enabled, and the CPU still scales after suspend/resume). As this only appears to affect the disk access, here's the dmesg output related to the SATA hardware and affected disk: ... ahci0: <Intel 5 Series/3400 Series AHCI SATA controller> port 0xb880-0xb887,0xb\ 800-0xb803,0xb480-0xb487,0xb400-0xb403,0xb080-0xb09f mem 0xf7cf7000-0xf7cf77ff \ irq 21 at device 31.2 on pci0 ahci0: AHCI v1.30 with 6 3Gbps ports, Port Multiplier supported ... ada0 at ahcich0 bus 0 scbus0 target 0 lun 0 ada0: <ST1000DM003-9YN162 CC4D> ATA-8 SATA 3.x device ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 953869MB (1953525168 512 byte sectors: 16H 63S/T 16383C) ada0: quirks=0x1<4K> ada0: Previously was known as ad4 On Fri, Sep 6, 2013 at 3:01 PM, Adrian Chadd <adrian@freebsd.org> wrote: > .. anything happening? > > > -adrian > > > On 2 September 2013 07:29, Adrian Chadd <adrian@freebsd.org> wrote: > >> >> On 2 September 2013 07:25, Mike Harding <mvharding@gmail.com> wrote: >> >>> It's detailed in the ticket, see >>> http://www.freebsd.org/cgi/query-pr.cgi?pr=181632 and search for >>> 'reverted'. >>> >>> >> Ok.
