Hi all, first off, I'm sorry to bother you with a slightly off-topic post, but I guess that the only real experts are around the Mactel community... :-)
About two weeks ago, I have set up an Intel Mac mini as a replacement of our old server. The operating system is Ubuntu 6.06, currently running a the standard Ubuntu 2.6.15-28-686 kernel (SMP). I chose Ubuntu mostly because I like the easy maintenance (which, with the long-term-support for 6.06 makes it an ideal server OS IMO), and because I'm familiar with Ubuntu. Installation went smoothly, and everything is running perfectly well... as long as the machine has some work to do. It seems that the Mac mini, after some period of inactivity, goes to sleep and doesn't properly wake up anymore. It does not react to network activity anymore, which is of course fatal for a server. Only a physical key press seems to wake the system up again. Afterwards, network latency is horrible (ping times of around 5 seconds) for a minute or two, after which the system "stabilizes" and works as normal -- until it decides to sleep again... :-( I have tried playing around with different kernel options (noacpi, noapic, apm=off and the like), but in fact they seem to not fix the problem (it still goes to sleep), but to even aggravate it, because the system then becomes terribly slow and throws strange error messages at me. I have also tried to disable powernowd, and to fiddle around with /proc/acpi/wakeup, which currently looks like this: [EMAIL PROTECTED]:~# cat /proc/acpi/wakeup Device Sleep state Status PXS1 4 enabled PXS2 4 enabled USB1 3 enabled USB2 3 enabled USB3 3 enabled USB4 3 enabled USB7 3 enabled All of this, unfortunately, did not help with the problem. I'm really lost now and begging for help... If anybody has any clue or hint, what could cause this behavior and how to fix it, please please help! Basically, a solution that would help me a lot would simply be a method to prevent the system from entering anything but a "100% on" state. I'm actually not really sure whether this has anything to do with ACPI at all, but I strongly believe so. Of course, the ideal solution would be a fully functional machine which actually makes use of the powersaving features it provides, but the "do not sleep at all" method would be sufficient for the time being to guarantee that the server is responsive at all times... Any thoughts are highly appreciated... Of course, I'll provide any other necessary information that could be helpful for troubleshooting. Thanks a lot in advance, best regards, Chris ------------------------------------------------------------------------- Take Surveys. Earn Cash.
