It would seem that perhaps my hangup problems in 2.6 aren't necessarily related to my US428. I got the 2.6.10-rc2 sources, and applied the mm3, rt2(Realtime LSM), Ingo's realtime-preempt, and usx2y 0.8.7.1 patches. The kernel patched and compiled fine, but it hangs after several minutes of normal web usage. I could still ssh into it(after a while that stopped working, too), and top showed several IRQ # processes running, which is abnormal. I'm not sure what else to look for, or what this means, exactly. Any ideas? should I be posting this to a different list? Thanks a lot, spencer
