Stefan, other PCI people.
An interesting situation worth knowing about. With this motherboard:
Gigabyte GA586A, rev 1.22C, based on the SiS 5571.
The Cyclades 16Ye board, based on the PLX PCI9060ES, does not function
correctly.
More specifically, after receiving the first interrupt (incoming
character, outbound character, change in handshaking state etc.) the
system locks up "moderately" tight - it still responds to ARP requests,
pings, etc., and CapsLock still works (but not NumLock?!), but no user
processes run, no console output, no disk activity etc.
These symptoms were observed consistently on a set of test hardware
comprising two Cyclades cards and two of the above motherboards.
Testing with Intel 430VX-based boards did *not* show the same symptoms.
We were unable to test with any other operating systems, as we don't
believe in congress with the devil. The Digital ethernet cards were
removed without effect.
For your perusal, here are the relevant parts of the system startup:
pcibus_setup(1): mode 1 addr port (0x0cf8) is 0x80000074
pcibus_setup(1a): mode1res=0x80000000 (0x80000000)
pcibus_check: device 0 is there (id=55711039)
Probing for devices on PCI bus 0:
configuration mode 1 allows 32 devices.

Any ideas? Complaints to SiS, PLX, Cyclades?
