From 950312ce22696ddfa42a957bdadaa9c24151e679 Mon Sep 17 00:00:00 2001 From: Andrew Randrianasulu Date: Thu, 14 May 2009 11:29:27 -0700 Subject: MIPS: IP32: Fix hang on shutdown in power button interrupt handler. The hang was caused by the use of disable_irq() from the interrupt handler itself. Fixed by the use of disable_irq_nosync(). The issue was triggered by: commit 3aa551c9b4c40018f0e261a178e3d25478dc04a9 Author: Thomas Gleixner Date: Mon Mar 23 18:28:15 2009 +0100 genirq: add threaded interrupt handler support Signed-off-by: Ralf Baechle --- arch/mips/sgi-ip32/ip32-reset.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/mips/sgi-ip32/ip32-reset.c b/arch/mips/sgi-ip32/ip32-reset.c index b6cab089561..667da932b7b 100644 --- a/arch/mips/sgi-ip32/ip32-reset.c +++ b/arch/mips/sgi-ip32/ip32-reset.c @@ -145,7 +145,7 @@ static irqreturn_t ip32_rtc_int(int irq, void *dev_id) "%s: RTC IRQ without RTC_IRQF\n", __func__); } /* Wait until interrupt goes away */ - disable_irq(MACEISA_RTC_IRQ); + disable_irq_nosync(MACEISA_RTC_IRQ); init_timer(&debounce_timer); debounce_timer.function = debounce; debounce_timer.expires = jiffies + 50; -- cgit v1.2.3
