Turning off SMP allows the card to work fine. Unplugging the SM-II pod also allows normal operation of the machine in SMP mode (of course then there are no serial ports to access). If anyone has suggestions, advice, or sympathy to offer it will be welcomed. DETAILS: occurs when a serial port on the cyclom board first accessed panic message = Panic: rslock: cpu 0: addr: 0xf026a3ec, lock 0x00000001 mp_lock = 00000001: cpuid = 0: lapic.id = 00000000 stack trace = #10 bsl1 () #11 cyopen (dev=12416, flag=5, mode=8192, p=0xf8ceae60) at ../../i386/isa/cy.c:755 further tracing has revealed that the panic actually occures in the commctl function in cy.c likely when a call is made to disable_intr() at line #2453. hardware = Tyan S1832DL Tiger 100 with dual Pentium II 350's 256 MB RAM, 18 GB IDE drive other: happens with both the isa and pci version of the card. -- Michael Scott Boers Datacomp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
