Subject: Panic in pci_call_probe from 2.6.18-mm2 and 2.6.18-mm3
Date: Sun, 08 Oct 2006 00:02:07 -0700 [thread overview]
Message-ID: <4528A26F.9000804@mbligh.org> (raw)
Not sure if you've seen this already ... catching up on test results.
This was on NUMA-Q, on both -mm2 and -mm3. -mm1 didn't suffer from this
problem.
Full logs:
mm2 - http://test.kernel.org/abat/50727/debug/console.log
mm3 - http://test.kernel.org/abat/51442/debug/console.log
config - http://test.kernel.org/abat/51442/build/dotconfig
I'm guessing from the 00000004 that the pcibus_to_node(dev->bus)
is failing because bus->sysdata is NULL. The disassembly and
structure offsets seem to line up for that.
#define pcibus_to_node(bus) (
(struct pci_sysdata *)((bus)->sysdata))->node
struct pci_sysdata {
int domain; /* PCI domain */
int node; /* NUMA node */
};
