Yep, it's the same. Today I got another lockup but this time I found the following log messages: kernel: ata1: command 0x35 timeout, stat 0x50 host_stat 0x24 looking around I found that disabling APIC might prevent this from happening so I'll give it a try. <div>> Have you tried upgrading to the kernel-2.6.16-1.2080? <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> -- fedora-list mailing list <a href="mailto:fedora-list@redhat.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">fedora-list@redhat.com</a> To unsubscribe: <a href="https://www.redhat.com/mailman/listinfo/fedora-list" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> https://www.redhat.com/mailman/listinfo/fedora-list</a> </blockquote> </div>
