Hi, I'm currently running kernel 2.6.9 with udev 0.034 and Debian's hotplug 0.0.20040329-15. I'm assuming this is a device driver bug and not a udev or hotplug bug because I'm pretty sure this worked fine in 2.6.8.1. My only hard drive on my IBM Thinkpad T41 has a primary partition, a logical partition, and an extended partition (hda1, hda2, and hda5). Both /dev/hda1 and /dev/hda2 show up as devices, but /dev/hda5 doesn't show up at all. If I create the /dev/hda5 manually with mknod, accessing it works fine. Below is the IDE-related output from dmesg on system startup, the output from lspci, and my kernel config.
