Revert "x86/ioapic: Restore IO-APIC irq_chip retrigger callback"
This reverts commit 020eb3daaba2857b32c4cf4c82f503d6a00a67de. Gabriel C reports that it causes his machine to not boot, and we haven't tracked down the reason for it yet. Since the bug it fixes has been around for a longish time, we're better off reverting the fix for now. Gabriel says: "It hangs early and freezes with a lot RCU warnings. I bisected it down to : > Ruslan Ruslichenko (1): > x86/ioapic: Restore IO-APIC irq_chip retrigger callback Reverting this one fixes the problem for me.. The box is a PRIMERGY TX200 S5 , 2 socket , 2 x E5520 CPU(s) installed" and Ruslan and Thomas are currently stumped.
