Do you received any report on problems using a cyclom 16Y on a pentium
200 Mhz??? We put together a system using linux kernel 2.0.27 (the one
that came in RedHat 4.1) a Adaptec 2940AU PCI SCSI card and a Realtek
based PCI network card and a PCI SVGA card (trident 9440), disabled PnP on
bios and put all irqs below 13 to "ISA legacy", we are using the correct
major/minor numbers and put the driver directly in the kernel (static, no
module for cyclades.c). The board freeze sometimes during the boot
sequence and sometimes goes on but minicom can't talk with /dev/ttyC?, any
ideas?? BTW I looked in drivers/char/cyclades.c and there's a
CYCLOM_16Y_HACK... could be this??? Just defining this it does a udelay
(10L) in cy_interrupt(int irq, void *dev_id, struct pt_regs *regs), could
be that the machine is too fast and we must enable this to sync or
