[Sitsofe Wheeler - Mon, May 26, 2008 at 03:04:54PM +0100] | <posted & mailed> | | When using a 32 bit linux-next-20080526 the bootup process will hang at a | random point (not even sysrq helps) with no additional output on the screen | (whereas linux-next-20080523 did boot). Mysteriously, booting with | nmi_watchdog=2 allows the boot to finish (booting with nmi_watchdog=1 still | stalls). I have bisected it down to commit | [d1b946b97d71423f365fa797d1428e1847c0bec1]: | | commit d1b946b97d71423f365fa797d1428e1847c0bec1 | Author: Cyrill Gorcunov <gorcunov@xxxxxxxxx> | Date: Sat May 24 19:36:34 2008 +0400 | | x86: nmi_32.c - add "panic" option | | Allow to pass "panic" option in 32bit mode | | Signed-off-by: Cyrill Gorcunov <gorcunov@xxxxxxxxx> | Cc: hpa@xxxxxxxxx | Cc: mingo@xxxxxxxxxx | Signed-off-by: Thomas Gleixner <tglx@xxxxxxxxxxxxx> | | Reverting this seemed to allow the boot to proceed without issue.
