Hello PCLinuxOS community!
Last weekend, I put together the following with the purpose of having a low-power computer for web surfing, downloading torrents, and occasional transcoding.
Motherboard: MSI E350IA-E45 (CPU is soldered to the board -- AMD Zacate-FT1 APU, dual core 1.6Ghz)
RAM: G.Skill 4GB DDR3-1333
PSU: Thermaltake Litepower 350W
SSD: Crucial M4 128GB
Casing: Rasurbo SC-08 m-atx
Monitor: Chimei 95ND 18.5" LCD
*no optical drives*
I installed only one OS: PCLinuxOS 2012.02 KDE. I fully updated through Synaptic, and afterwards installed kernel 3.2.18 pae.bfs. Rebooted and everything works fine.
The problem is when I do a shutdown, it shows the "Shutting down the system" screen but it doesn't really power down the computer...unless I press and hold the case's power switch.
After searching this forum, I made some changes in /boot/grub/menu.lst --
I changed acpi=on to acpi=force and also modified splash=silent to splash=verbose and removed the "quiet" option so I could see what's going on when the computer is shutting down.
The result of the verbose shutdown is everything appears OK (all processes killed, file systems unmounted) and the last lines to be displayed are:
And at this point, the computer freezes.
I notice the shutdown freeze at power down only happens when I've been using the computer for a long-ish time...say, for more than 30 minutes. But if I boot into the desktop, stay for only 5 minutes and then shutdown, the freeze at power down doesn't happen.
FWIW, I also changed the following in Configure Your Desktop > Hardware > Power Management > Power Profiles -- I unchecked all boxes re: Dim display, etc. The motherboard is only 18W TDP so I am not overly concerned about power savings -- but the freeze at power down still happens.
Appreciate your help.
