Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Anyone got any good tips on how to debug a SMP system that is locked up in a deadlock situation in the kernel? I'm working on a kernel module, and after some number of hours of stress testing, the box locks up. None of the sysrq options show anything on the display, though the reBoot option does reboot the system. RedHat 6.2 and its 2.2.14 kernel. Doesn't hang for me on 2.4, so I need to debug it here... Any hints? thx.bri. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
