From: Kei Tokunaga <ktokunag@redhat.com> Subject: [RHEL5 PATCH 5/5] pciehp: 'Trying to free already-free IRQ XX' is reported Date: Wed, 29 Nov 2006 12:41:48 -0500 Bugzilla: 216940 Message-Id: <456DC65C.5080503@redhat.com> Changelog: pciehp: free_irq called twice BZ216940 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=216940 This fix was posted to the community, and is waiting for being merged to upstream. It already got "Signed-off-by:" from the maintainer. This patch fixes the problem that the following error message is reported when pciehp driver is rmmoded. Trying to free already-free IRQ XX The cause is that pciehp driver is doing unnecessary 2nd free_irq at driver unloading. This patch removes this call. This patch applies to -2.6.18-1.2747.el5 and I have verified that it worked all right.
