On a fresh Fedora 11 install (HP nc8000 laptop, 1.6 Ghz Pentium M), the
Planet CCRMA kernel-rt-2.6.29.6-1.rt23.2.fc11.ccrma.i546.rt freezes on
boot with:
Starting udev: end_request: I/O error, dev fd0, sector 0
Buffer I/O error on device fd0, logical block 0
Isn't fd0 a floppy drive? There isn't one in this machine. There /is/
one across the room on a shelf -- maybe rt23 doesn't like that ;)
I disconnected all usb drives and peripheries, but no luck.
It's not a major drama, as 2.6.29.5-1.rt22.1.fc11.ccrma.i586.rt works
perfectly, as does stock Fedora kernel 2.6.29.5-191.fc11.i586.

I'm inclined to think that this error (end_request, Buffer I/O) is quite
normal for a laptop that presents a floppy drive to the kernel via the
BIOS yet doesn't have one ... and your real problem is that udev is
failing to proceed.
Does the error also get logged in dmesg during
2.6.29.5-1.rt22.1.fc11.ccrma.i586.rt or 2.6.29.5-191.fc11.i586.?

Thanks for the insight.

Not as far as I can tell -- there's no output for `dmseg | grep
end_request' with either.

Hmm, that's unfortunate. This suggests the end_request error really is
relevant to the hang. I'll now grasp at straws. For a more rigorous
response log a bug with the guys who made that kernel build.
1. see if there is a BIOS version update.
2. see if there is a BIOS setting for "disabling" the floppy drive,
even though it isn't physically present.
3. if the system has hald running, (obviously with a working kernel),
then try disabling polling on the non-existent floppy drive ...
% sudo hal-disable-polling --device /dev/fd0
