The last kernel message on the console is: adb: starting probe task... At this point the kernel hangs and doesn't respond to any attempt to invoke SYSRQ or XMON. Normally the subsequent messages would be: adb devices: [2]: 2 5 [3]: 3 1 ADB keyboard at 2, handler set to 3 Detected ADB keyboard, type ISO, swapping keys. input: ADB keyboard on adb2:2.05/input ADB HID on ID 3 not yet registered ADB mouse at 3, handler set to 2 input: ADB mouse on adb3:3.01/input adb: finished probe task... The 2.6.11-rc1 kernel also hung on an eMac (G4). On that machine it appears the hang occurred in radeonfb: the screen flickers off/on during radeonfb initialisation, but with 2.6.11-rc1 the screen just went black. Afterwards the eMac did not respond to any keyboard or network activity, so I have to assume it hung hard. I've traced the cause of the hangs to a local_irq_disable() added to init/main.c:rest_init() in 2.6.10-bk12. Removing it eliminates the hangs on both the G3 and the eMac: diff -rupN linux-2.6.11-rc2/init/main.c linux-2.6.11-rc2.ppc32-nohang-fix/init/main.c --- linux-2.6.11-rc2/init/main.c 2005-01-22 12:08:14.000000000 +0100 +++ linux-2.6.11-rc2.ppc32-nohang-fix/init/main.c 2005-01-22 13:55:07.000000000 +0100 @@ -377,7 +377,7 @@ static void noinline rest_init(void) * Re-enable preemption but disable interrupts to make sure * we dont get preempted until we schedule() in cpu_idle(). */ - local_irq_disable(); +// local_irq_disable(); preempt_enable_no_resched(); unlock_kernel(); cpu_idle(); The hangs occured with unpatched vanilla kernel sources, and I used a simple no-frills .config with SMP and PREEMPT both off. /Mikael #
