| |
Hi Linus and Co.,
I am writing to let you know that in all test12-pre6+ kernels, I get a "Bad PCI invocation" error when hotplug attempts to handle the insertion of a USB host-controller into a Cardbus slot.
I am aware that you most likely will ship 2.4.0 anyway, but thought you should at least know about the bug.
I have tried your latest call_usermodehelper patch, Andrew, which appears to have not made it into the kernel, but it did not solve the problem.
What follows is test results from three configurations:
prerelease with ds.o as a modular driver -- hotplug fails prerelease with ds.o in-kernel -- hotplug fails test11 with ds.o as a modular driver -- hotplug succeeds and usb-ohci loads
At the end of the message, you'll find the lspci output for the BusPort Mobile generated using prerelease.

Here is what lspci has to say about the BusPort PCI entry when running prerelease. I checked the lspci output running under test11 and found no discrepancies.
