We have ben doing this for 3+ years using various version of OpenBSD. A couple of weeks ago, I replaced one of these amchine (which was an older P1) with a newer PII'. Shortly after that it started locking up almost every day. The symptom was always the same, a starnge checkerboard looking pattern on the monitor, and absolute hard lockup. Need to pll the poer cord to reset the machine. I fiddles around a while, and changed various parts on this amchine, but never did solve the problem. Then about a week ago, I replaced that machine with a totaly different one. The original "bad" machine passed memory, and hard drive tests, and has been running in the lab WO crashing for almos a week now. Yesterday, the "new" machine locked up in the exact same way. Help! Foes anyone have any ideas? Are there any know issues with 4.10, and serial ports? Thanks for any input whatsover. -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin
