This suggests that processor.max_cstate=2 is a good candidate for a workaround. Please boot on DC with CONFIG_ACPI_PROCESSOR=y (not =m) and this cmdline param and see if the hang goes away. If it does, then CPU_IDLE's C3 code is implicated. In any event, a hang in the device probe part of kernel boot usually smells like an interrupt problem... -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
