From 0f261ede311bfd718d84bdf50dd7fcee585e82c7 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Wed, 8 Feb 2012 15:32:13 +0100 Subject: [IA64] disable interrupts when exiting from ia64_mca_cmc_int_handler() SAL specification mandates that ia64_mca_log_sal_error_record() gets called with interrupts enabled, and that's why ia64_mca_cmc_int_handler() is enabling them. It however forgets to re-disable them when exiting, which triggers WARN_ON() in generic IRQ handler. Disable the interrupts again before exiting. This is analogous to a3967685745 ("[IA64] disable interrupts at end of ia64_mca_cpe_int_handler()").
