Thanks Jeff for the quick response. All suggestions written down on hard copy for future reference. These acpi related shutdown problems are a real nightmare to resolve. Not everyone is affected. it just seems to happen on some hardware, and later kernels. for example on one of my 2 machines, an old Gateway 500, P111 (katmai), Fc5 shutsdown completely whichever kernel I've booted up with. On a later I-friend machine, FC5 will shutdown completely if I boot with the original 2.6.15 kernel, but booting with revisions of the 2.6.17 kernel, and later, I have to add acpi=force to the kernel line to get it to shutdown completely. My Debian Etch, and Lenny installs on the I-friend machine are using a 2.6.17 kernel, but may be an earlier revision than the FC5 one, and I don't have any shutdown problems with my Debian installs. I'll try and find later kernels for Etch, and Lenny to see if the shutdown problem shows up. Mind you, saying this, a bug report for Ubuntu to Launchpad showed acpi related shutdown problems with 2.6.15 kernels. Many suggestions to append the kernel line with, some worked, others didn't. It's all a bit bizarre. Thanks again for your help. Nigel. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
