Thank you Remy! Your recommendation solved the problem. Its been running for over a day now without a single hiccup.
thanks also to everyone else who took time to respond with help and suggestions. At the risk of being a bother, were you able to get all four ethernet devices working? on mine, only the first two are working. the other two get errors on ioport allocation. em2: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> mem 0xfdbe0000-0xfdbfffff irq 61 at device 1.0 on pci8 em2: 0x40 bytes of rid 0x20 res 4 failed (0, 0xffffffffffffffff). em2: Unable to allocate bus resource: ioport em2: Allocation of PCI resources failed device_attach: em2 attach returned 6 em2: <Intel(R) PRO/1000 Legacy Network Connection 1.0.6> mem 0xfdbc0000-0xfdbdffff irq 62 at device 1.1 on pci8 em2: 0x40 bytes of rid 0x20 res 4 failed (0, 0xffffffffffffffff). em2: Unable to allocate bus resource: ioport em2: Allocation of PCI resources failed device_attach: em2 attach returned 6 ron. ----- Original Message ----- From: "Remy Nonnenmacher" <[email protected]> To: [email protected], [email protected] Sent: Tuesday, March 17, 2015 4:39:33 AM Subject: Re: sun x4500 and smp Hi Ron, Fighted the same problem on mine. It seems to be a problem of interrupts dynamic routing on those old good opterons. I fixed it by sticking all interrupts to processor 0 (cpuset -l 0 -x ..). Since then, it works without any trouble.
