I have several IBM x series servers at work and one of my machines |
| 2 |
drives seem to be acting up a bit. I get a major loss in system time |
| 3 |
and performance. |

My dmesg tailed.. |

Losing too many ticks! |
| 37 |
TSC cannot be used as a timesource. |
| 38 |
Possible reasons for this are: |
| 39 |
You're running with Speedstep, |
| 40 |
You don't have DMA enabled for your hard disk (see hdparm), |
| 41 |
Incorrect TSC synchronization on an SMP system (see dmesg). |
| 42 |
Falling back to a sane timesource now. |

spurious 8259A interrupt: IRQ7. |

This machine is our continues build environment that builds out |
| 54 |
several instances of our app and is under extreme load at times. I am |
| 55 |
wondering if this is a sign of a bad drive or if this has something |
| 56 |
to do with overload. |
| 57 |
|
| 58 |
I am able to enable dma after the fact with hdparm. I do not run any |
| 59 |
special hdparm option at boot. The only thing I do is build the ide / |
| 60 |
drive options in to my kernel. |
| 61 |
|
| 62 |
Any suggestions would be great. |

Thanks, |
