From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030701 Galeon/1.3.9 Description of problem: I suspect this should be filed in the kernel.org bugzilla, but I'm filing it here first. (In other words, feel free to punt it.) I added the following config entries to the test7 i686 config: CONFIG_SOFTWARE_SUSPEND=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_SLEEP_PROC_FS=y and changed the ACPI bits (AC, BATTERY, BUTTON, FAN, PROCESSOR, THERMAL) from modules to in-built. I've run into several bugs related to switching to sleep mode S1, but they've already been reported. This bug, however, I haven't found any mention of anywhere (kernel.org's bugzilla, redhat's bugzilla, or google) Version-Release number of selected component (if applicable): kernel-2.6.0-0.test7.1.52 How reproducible: Always Steps to Reproduce: 1. modify the kernel config as described above, rebuild and install 2. echo 4 > /proc/acpi/sleep Actual Results: the last few lines displayed are: hda: completing PM request, suspend waiting for DMA's to settle down... double fault, gdt @ c02ed900 [255 bytes] double fault, tss @ c0361800 eip=c024731e, esp=0 eax=0, ebx=0, ecx=0, edx=0 esi=0, edi=0 And the machine stops responding.
