after having installed a new gentoo-system to my pc, i recognized the login into kde4 lasting longer than normal. dmesg told me, that the sata controller is being reinitialized. after reinitializing the sata port, the login proceeded as expected a i never had a problem with the sata port being reinitialized again. except logging into kde4 again (user independent). i am using kde-4.4.5 and gentoo-sources-2.6.35-r4. downgrading to pm-utils-1.3.0-r2 fixed the problem.

What's the status here, does this still happen? More important, does it still happen with kde-4.6.2?
Yeah it still does so, and we should fix it, Add it to block the stablereq, it is quite annoying but i didnt figure how to solve it.
Fixed in 1.4.1-r2.
I don't think that the link reset is caused by SATA ALPM - in my tests it is `hdparm -W 0/1` (enabling respectively disabling drive write cache) that causes it and it is rather in power.d/harddrive. This can be fixed by setting default DRIVE_WRITE_CACHE_{AC,BAT} to empty string in power.d/harddrive - hdparm then just prints current value and it can be still configured by user in /etc/pm/config.d. (by the way, other defaults in power.d/harddrive also do not seem safe, but that would be another bug)
