I am still running 2.1.125 on my PowerBook G3, and get tons of bogus interrupts. I am trying to upgrade to 2.1.130 (or the latest vger tree). When I run 2.1.130, I don't see the problems. The major difference is I run the IDE DMA on 2.1.130 and not on other kernels..........I can't point to anything else. My other thought was something wrong with power management. > I never experienced the slowdown+crash on heavy i/os, even when copying > full kernel trees locally, over NFS and both at the same time.

I boot with OF (either floppy or enet) because I don't have an easy way to get the kernel into the MacOS system folder. I have hacked the atyfb to force G3 resolution and depth regardless of what it finds automatically. -- Dan [[ This message was sent via the linuxppc-dev mailing list.
