Hello Robert If Linux doesn't boot "out of the box" on your system w/o any boot parameter workarounds, it is a Linux bug. So if this is still true, please file it here: http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI It sounds like you are seeing a big difference between "acpi_osi=Linux" (default for 2.6.22 and earlier) vs. "acpi_osi=!Linux" (default for 2.6.23 and later) Is this still true? please send me the output from acpidump. thanks, -Len ps If you don't have acpidump, you can get it from pmtools here: http://www.lesswatts.org/projects/acpi/utilities.php System Information Manufacturer: Hewlett-Packard Product Name: Presario F500 (GF596UA#ABA) Version: Rev 1 Serial Number: CNF72342QC UUID: 434E4637-3233-3432-5143-001B244CFD1C Wake-up Type: Power Switch SKU Number: GF596UA#ABA Family: 103C_5335KV Handle 0x0002, DMI type 2, 8 bytes Base Board Information Manufacturer: Quanta Product Name: 30D3 - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
