PXE Boot Crashes in ipro1000 Driver
|Reported by:||bonefish||Owned by:||axeld|
When booting via PXE with the ipro1000 driver responsible for the network adapter, two instances of the driver are loaded: The first one from the netboot archive, the second one from the boot disk, when it has been mounted. Somewhere in its uninit_driver() the second instance causes a page fault.
I'm not sure who's to blame. The driver probably shouldn't be loaded a second time (devfs) and only one driver should be allowed to play with the hardware (device manager?), but, unless I'm mistaken, the situation didn't really change in this respect since PXE support was added, and it worked once.
Removing the driver from the disk image avoids the problem, as expected.
Attached is the serial debug output. The "add_driver()" lines originate from devfs:add_driver(), where I added the respective dprintf().
