Hello, I've a trouble with new achi driver on currently 9 release, but it was the same on 8-stable. I've have an:
smartctl -a /dev/ada0 === START OF INFORMATION SECTION === Model Family: Western Digital Scorpio Blue Serial ATA Device Model: WDC WD3200BEVT-22A23T0 Serial Number: WD-WXL1AB086780 And there's an idle state disabled by wdidle3 v1.05. But it constantly goes to power saving mode. I can see it 'cos I'm hearing a sound of spinning up HDD and SMART param 193 Load_Cycle_Count rises VERY frequently, something insane about one per few minutes. This thing solves the problem: camcontrol cmd ada0 -a "EF 85 00 00 00 00 00 00 00 00 00 00" and everything goes fine from that moment. Output with disabled APM. camcontrol identify ada0 pass0: <WDC WD3200BEVT-22A23T0 01.01A01> ATA-8 SATA 2.x device pass0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) protocol ATA/ATAPI-8 SATA 2.x device model WDC WD3200BEVT-22A23T0 firmware revision 01.01A01 serial number WD-WXL1AB086780 WWN 50014ee6565acc41 cylinders 16383 heads 16 sectors/track 63 sector size logical 512, physical 512, offset 0 LBA supported 268435455 sectors LBA48 supported 625142448 sectors PIO supported PIO4 DMA supported WDMA2 UDMA6 media RPM 5400 Feature Support Enabled Value Vendor read ahead yes yes write cache yes yes flush cache yes yes overlap no Tagged Command Queuing (TCQ) no no Native Command Queuing (NCQ) yes 32 tags SMART yes yes microcode download yes yes security yes no power management yes yes advanced power management yes no 254/0xFE automatic acoustic management yes no 254/0xFE 128/0x80 media status notification no no power-up in Standby no no write-read-verify no no unload yes yes free-fall no no data set management (TRIM) no And finally i've got in /boot/loader.conf: hint.ahcich.0.pm_level=0 I'd like to know how to permanently disable this APM mode because it's killing my HDD. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
