The only thing I have done that seems to have made a difference is that I have switched 2.6.18-53.1.14.el5xen to 2.6.18-53.1.14.el5. I am still getting the following log entries : May 8 08:23:14 DeGw kernel: ipp[11677]: segfault at 0000000000000000 rip 00002aaaabf2abc0 rsp 00007fff7b7ff6b8 error 4 May 8 08:28:26 DeGw kernel: ipp[12925]: segfault at 0000000000000000 rip 00002aaaabf2abc0 rsp 00007fffa5ab6988 error 4 However I have only received 7 of these since last night instead of hundreds while running xen. When I booted the system last night with 2.6.18-53.1.14.el5 I received some additional "messages" log entries : May 8 01:50:00 DeGw kernel: irq 193: nobody cared (try booting with the "irqpoll" option) May 8 01:50:00 DeGw kernel: May 8 01:50:00 DeGw kernel: Call Trace: May 8 01:50:00 DeGw kernel: <IRQ> [<ffffffff800b703a>] __report_bad_irq+0x30/0x7d May 8 01:50:00 DeGw kernel: [<ffffffff800b726d>] note_interrupt +0x1e6/0x227 May 8 01:50:00 DeGw kernel: [<ffffffff800b677f>] __do_IRQ+0xc7/0x105 May 8 01:50:00 DeGw kernel: [<ffffffff80011cc5>] __do_softirq +0x5e/0xd5 May 8 01:50:00 DeGw kernel: [<ffffffff8006b3bd>] do_IRQ+0xe7/0xf5 May 8 01:50:00 DeGw kernel: [<ffffffff80069d0e>] default_idle+0x0/0x50 May 8 01:50:00 DeGw kernel: [<ffffffff8005c615>] ret_from_intr+0x0/0xa May 8 01:50:00 DeGw kernel: <EOI> [<ffffffff80069d37>] default_idle +0x29/0x50 May 8 01:50:00 DeGw kernel: [<ffffffff80046fb1>] cpu_idle+0x95/0xb8 May 8 01:50:00 DeGw kernel: [<ffffffff803d3806>] start_kernel +0x220/0x225 May 8 01:50:00 DeGw kernel: [<ffffffff803d3237>] _sinittext +0x237/0x23e May 8 01:50:00 DeGw kernel: May 8 01:50:00 DeGw kernel: handlers: May 8 01:50:00 DeGw kernel: [<ffffffff801dc154>] (usb_hcd_irq+0x0/0x55) May 8 01:50:00 DeGw kernel: Disabling IRQ #193 If any of you can help me get a start on this problem I would sure appreciate your help.
