Seems it's still the same behavior in Maverick as it was before in Lucid.
The original hard drive delivered with the Notebook was from Hitachi, so maybe there is some kind of incompatibility between the controller/BIOS and the WD drive. If I find some time, I'll insert the original one and repeat the test.
My hardware details:
Lenovo T61, 7664-18G with BIOS Version 2.26
$ lspci -vvnn |grep -i sata
00:1f.2 SATA controller [0106]: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller [8086:2829] (rev 03) (prog-if 01 [AHCI 1.0])
Hard drive is:
$ smartctl -a /dev/sda
Model Family: Western Digital Scorpio Blue Serial ATA family
Device Model: WDC WD5000BEVT-00ZAT0
Firmware Version: 01.01A01
Kernel is:
$ uname -a
Linux redlap 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux
When I do
$ echo "min_power" > /sys/class/ scsi_host/ host2/link_ power_managemen t_policy
there is no message from the kernel.
Switching back to
$ echo "max_performance" > /sys/class/ scsi_host/ host2/link_ power_managemen t_policy
the following messages appear:
