* [bugme-daemon@bugzilla.kernel.org: [Bug 7306] Yenta-socket causes oops on insertion of any PCMCIA card] @ 2008-07-17 9:14 Dominik Brodowski 2008-07-29 18:28 ` Dominik Brodowski 0 siblings, 1 reply; 3+ messages in thread From: Dominik Brodowski @ 2008-07-17 9:14 UTC (permalink / raw) To: linuxppc-dev 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 ----- Forwarded message from bugme-daemon@bugzilla.kernel.org ----- Subject: [Bug 7306] Yenta-socket causes oops on insertion of any PCMCIA card To: linux-pcmcia@lists.infradead.org From: bugme-daemon@bugzilla.kernel.org Date: Thu, 17 Jul 2008 01:45:44 -0700 (PDT) http://bugzilla.kernel.org/show_bug.cgi?id=7306 ------- Comment #17 from linux@brodo.de 2008-07-17 01:45 ------- 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? -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ Linux PCMCIA reimplementation list http://lists.infradead.org/mailman/listinfo/linux-pcmcia ----- End forwarded message ----- ^ permalink raw reply [flat|nested] 3+ messages in thread

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).
