kernel BUG at fs/sysfs/file.c:381

[Dumitru Ciobarcianu]

Hello,

While trying to install an PCI to PCMCIA adapter (an PCI card with an TI
cardbus bridge on it) I stumbled upon this kernel bug and captured it
with an serial console:

I tried various kernel parameters (acpi=off, pci=routeirq,
pci=usepirqmask) but all give the same result.

Is there any workaround for this?
