[bugme-daemon@bugzilla.kernel.org: [Bug 7306] Yenta-socket causes oops on insertion of any PCMCIA card]

[Dominik Brodowski]

Hi,

on an Apple Powerbook G3 (Lombard) with a PPC 740 running at 333 MHz, the
PCI host bridge is condigured to allow "downstream" devices to use iomem

0xfd000000 - 0xfdffffff

However, when using it for PCMCIA purposes, there's a machine check. Any
ideas on why this PCI host bridge is mis-configured, and how to resolve this
issue (besides adding reserved=0xfd000000,0xffffff as kernel boot option)?

Best,
	Dominik

Now this contains interesting information:

pcmcia: parent PCI bridge Memory window: 

means the PCI host bridge is configured to allow "downstream" devices to use
this memory area. However, when the PCMCIA socket tries to do so, you get the
machine check. So my question would be to the powerpc folks: why is the PCI
host bridge configured this way, even if this memory area is not usable?

Strange. Paul has a lombard, so if he can bring it to the office, I'll
have a look. Paul, bring some legacy PCMCIA cards too if you have any,
I'm not sure I do (though I think we have one or two somewhere in the
lab).

Cheers,
Ben.
