Hi all, I thought I've found all issue with that new box but I was wrong ;) On an ASUS P5E-VM DO , 4G RAM , Q9300 CPU after suspend to ram Thermal Subsystem gets corrupted in some way. I got some reboot , halt problems and was hunting the issue and noticed these problems only occurred when I've suspend the box to ram , at least once. I've tested 2.6.{24*,25,linus-git(before ACPI merge),x86-latest-git} and all got that problem. Also on x86-latest-git I've tested with MTRR_SANITIZER on/off. It does not make any difference. lspci output before s2r is : .. 00:1f.6 Signal processing controller [1180]: Intel Corporation 82801I (ICH9 Family) Thermal Subsystem [8086:2932] (rev 02) Subsystem: ASUSTeK Computer Inc.
