2.6.10-mm1 panic in sysfs ?

[Badari Pulavarty]

Hi Andrew,

I get a panic in sysfs_readdir() while booting 2.6.10-mm1
kernel. Known fixes ?

Thanks,
Badari

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically.  If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device().  As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior.  If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@xxxxxx
** so I can fix the driver.
