Since this looks like an ACPI issue, I checked the ACPI website: http://acpi.sourceforge.net/
Their bug tracking system asks that you /not/ report bugs there that aren't vanilla kernels. (I suspect the Ubuntu one isn't). However, they do provide details about what debugging feedback they need to track down issues: * The output from dmesg -s40000 or the serial console log * The output from dmidecode, available in /usr/sbin/ or at savannah.nongnu.org or at kernel.org * The output from acpidump, available in /usr/sbin/ or in the PM Tools at kernel.org * Please attach the output from lspci -vv and cat /proc/interrupts ( In the HTML version on the site, they provide links to get the non-standard utilities they reference ). So to the other bug reporters: It would be useful if you post requested details about your systems. With some of that gathered, perhaps we could point the ACPI developers to this ticket and they would be willing to help. (Since I'm also experiencing a similar regression on new Mandriva's I assume this is actually an upstream issue and not a Ubuntu issue. ) Thanks!
