Date: Sun, 30 Mar 2008 20:39:18 +0200 From: Pierre Ossman <drzeus-list@...eus.cx> To: LKML <linux-kernel@...r.kernel.org> Cc: Greg KH <greg@...ah.com> Subject: some PCI reads makes machine lock up I got a really weird bug report where loading the sdhci driver makes the machine lock up. Some further debugging revealed that simple reads into the device's address space causes the problem (reads that aren't supposed to trigger any activity). To make things even more confusing, it's the pattern of the reads, not reading specific registers. As my knowledge of the low level PCI stuff is very limited, I was hoping that someone with more expertise could have a look at it and suggest some things to test. The bug is in the kernel bugzilla here: http://bugzilla.kernel.org/show_bug.cgi?id=9905 Rgds -- -- Pierre Ossman Linux kernel, MMC maintainer http://www.kernel.org PulseAudio, core developer http://pulseaudio.org rdesktop, core developer http://www.rdesktop.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
