Did you create a high load on the system in the manner I described? The bug once only appeared after about 6 hours here when line + CPU had been mostly idle. But that was the longest time between failures. Can you test with one of the 2.6.16 kernels I tried (latest was .9)? Can't say for sure if CPU load is a factor, load on the connection seems to be. After using 2.6.15.7 for another 5 days now with some more stress testing, I can assure that 2.6.15 definitely does not produce any dropouts on this machine. For now I'll try to reproduce the effects on my second box (AMD64/nf4). I'd be happy if someone could give me some hints on which patches I could try to revert as the changes to ppp between the two versions look fairly harmless. For the first time in 8.5 years, I cannot use a 'stable' kernel release and there is really nothing special about this system. Regards, Nuri
