In an earlier post to the list I described a hard lockup condition that occurs on linux kernels 2.4.22, 2.6.13, and 2.6.17 when using a 4 port 10/100 fast ethernet card. The lockup is easily repeatable and occurs on 2 out of 3 computers. Further testing has revealed that the lockup can be preve

lowlatency 2.2.19

2001-06-03 Thread William Montgomery
I am testing Ingo's lowlatency patch on the 2.2.19 kernel and have a strange problem. I applied the most recent patch I could find, lowlatency-2.2.16-A0 and fixed a few failed hunks. The kernel appears stable after many (~24) hours of stress testing with Benno's latencytest suite and others.
