Date: Tue, 23 Apr 2002 00:19:23 -0400 Sender: linux-smp-owner@vger.kernel.org Message-ID: <201921.1019521163@[10.1.1.3]> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Content-Disposition: inline List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: linux-smp@vger.kernel.org Have been having apparently random lockups on an ibm netfinity 7100. The only messages generated have been the following in dmesg. ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up timer (IRQ0) through the 8259A ... failed. ...trying to set up timer as Virtual Wire IRQ... works. added the following: append = "nmi_watchdog=0" to the lilo.conf file and the lockups seemed to have subsided. 17 days up! woo-hoo. Anyway just curious about the wierd science behing this problem and if I can expect it to go away completely. BTW kernel version 2.4.18 and please reply off list as I am not subscribed. Thanks for any help. Andy andy erickson, emji 919-545-2539 andy@emji.net
