I just aware the AHCI mode didn't enable on your machine, did you try to enable AHCI mode before?
Host gx280 is a Dell Optiplex GX280, service tag 20HRT71. I've never found the string "AHCI" in any Dell BIOS setup utility. This one has a choice for SATA operation between "Normal" and "Combination". Whether "Normal" is supposed to provide AHCI I have no idea.
hmm....... I just google 'Dell Optiplex GX280' this model, the 'Combination' means SATA/PATA combination mode, the 'Normal' is only SATA mode. So, the BIOS of this machine doesn't support AHCI, at least no BIOS option can enable it.

device power on through many reboots in part because of the sparsity of errors since initializing this bug. Maybe the root problem is a need for the device to warm up more than briefly before it's completely ready to use.
Do you mean power up the eSATA box before power on computer?
Of course. I have no systems that fully support eSATA (nothing hot-pluggable), so to make sure I cause no hardware damage, I make a point to only turn on external device power while the system it is connected to is powered off.
I have a Philips external eSATA box, and I plugged it to a eSATA port on HP notebook, tried warm-boot/cold-boot a couple of times, but didn't reproduce issue.
I have multiple eSATA devices. None except the newest gives any trouble. I suspect the v2 model to have cost-cutting (defective or missing) features and/or firmware over v1 models that cause this.
Last boot used libata.force=5.0:noncq. Before trying to get it to error, I issued 'shutdown -h 00:59' to give me time for make it error but allow it to possibly shut down properly after errors occurred. I got it to error briefly on tty10 before ro on / occurred, so there are a few errors in /var/log/messages on 12.2M3 / filesystem now. It appeared to shutdown properly, but did not power off. I'm going to boot from live CD now and will comment more when I'm ready to attach useful logs.
The NCQ feature only works on AHCI mode, but it still works to me when I switch to IDE mode on my HP notebook. I didn't see 'libata: Unknown parameter' message. The 'libata.force=5.0:pio4' kernel parameter still worth a try, switch it to PIO mode avoid DMA problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
