sys/i386/isa cy.c
Log:
Fail the probe instead of panicing if the memory address is 0. The
memory address can be 0 only with certain misconfigurations. We don't
try to detect misconfigurations of the kernel config file, but IIRC the
panic was caused by a hardware misconfiguration like the following:
- a cy PCI card physically present but with a hardware conflict
- then the cy PCI probe is called first but fails due to the conflict
- no cy ISA card present
- the cy ISA probe is called. Normally this uses the nonzero memory
address in the config file and just fails when there is no cy ISA
card present, but when there is a cy PCI card present, the ISA memory
resource is apparently lost. The (non-)presence of the cy ISA card
probably makes no difference here.
