Subject: Cyclades Cyclom-Ye panics with 3.1's SMP

SUMMARY:
My cyclades cyclom-Ye panics the kernel when I am running with
release-3.1's smp options. 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.
