FWIW, I responded to this on Usenet and basically blamed his hardware. I've used PLIP to mount NFS disks and done build worlds on the two laptops I have, one a 486/75, and the other a Pentium/75. The 'servers' have been my 486/66 at home and my P-100 ASUS box at work, and I've never seen any problems with the timers dying. NFS mounting the disks over PLIP was a *really* good way of generating an incredibly high interrupt load on my 486/66, although the Pentium didn't seem to mind it as much. Both laptops seemed to not notice it much since I suspect they were CPU and/or I/O bound most of the time. Nate
