From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Something is preventing shutdown... (slrpnk.net)

Does anyone how how I can diagnose and fix this problem:

Sometimes, but not always, when shutting down the process does not actually complete and the computer does not turn off.

The screen turns off but the keyboard backlight is still responsive, the fan is still going and the power-on LED is lit. Because the screen is turned off I can't interact graphically with the computer and have to just hold down the power button and do a hard reboot.

I haven't tested it properly but I get the feeling it happens more often if I have been doing audio work.

When it happens, try pressing Alt + SysRq(/PrtSc) + o. If that turns off your computer, then the kernel is still running and something is preventing shutdown; if it doesn't, either SysRq is disabled, or ACPI is broken.
