| |
Hi
On a lightly loaded machine, I don't see any performance difference with CSLIP with 1.3.7x compared to any other kernels so I can't try to track this down myself. For those people experiencing SLIP/PPP problems here are some ideas/questions:
1) Has anyone tried the techniques from Documentation/BUG-HUNTING to track down exactly which patch introduced this problem.
2) Can anyone reproduce this under more precise conditions i.e. where you are not dependent on your phone company or ISP ... perhaps to see if the problems still exist running say minicom between two linux boxes connected via a serial cable ...
3) Anyone got an oscilloscope and a signal generator? A few lines of kernel code to hook the printer port interrupt and toggle a printer port line should enable you to measure interrupt latencies ...
4) Is there any commonality between the reports i.e. does everyone use say IDE or SCSI or whatever ...
Comments?
