I expected you to go back and look at the prior transactions in the
netbsd-help discuss meeting...

At the time I had been operating under the assumption that this
was a 1.1 problem; now that I think about it might have been a 1.0A
install, in which case we should punt on explaning it, I guess. Sorry.
Here's the original message anyway.

} Anyway:
}
} My problem right now is as follows: Once I finally got my network card
} to work, I noticed that the machine would freeze unexpectedly in X
} during periods of
} high disk and mouse activity. Sometimes, the machine will freeze while the
} hard disk is being accessed, resulting in the hard disk activity light to glow
} steadily. I imagine that this is not good.
} I suspected an IRQ conflict, especially since I
} don't have this problem in ttymode sessions and my current "fix" is to turn
} the mouse upside down in X and use it as little as possible. After spending
} a long time, I managed to prepare the machine to crash in X while I switched to
} ttymode. I then got an error message:
}
}
} kernal: non-maskable interrupt trap, code=0
} stopped at _sendsig+0x9c:movl % ecx, 0xffffffc4(%ebp)
}
}
} I have been able to reproduce this message.
} I've already tried reconfiguring mouse and video protocols in several
} ways. I took out my sound card (which eats up 3 IRQs by itself) and got the
} same problem.
}
} My mouse is on com1 irq3. The other irq-looking things I've seen at
} startup are as follows:
}
} w 0 at irq 4
} com1 irq 3 (the mouse)
} lpt0 irq 14
} isa0 irq 10
} isa0 irq 1
}
}
}
}
}
} I hope you can help, and I hope the class is still available.
