Red Hat Bugzilla – Bug 511157
Udev loads too long on boot

Description of problem:
After upgrading udev to version in test-updates, it loads 3 minutes. After changing kernel option from `quiet' to `udevinfo' and option in udev.conf to `info', screen is flooded with informations from udev, while it loads on boot. Informations scroll too fast to read anything.
Version-Release number of selected component (if applicable):
udev - 141-4.fc11
kernel-PAE - 126.96.36.199-191.fc11
Steps to Reproduce:
Udev loads too long.
Udev loads quickly.
I'm attaching my boot.log, but it shows only the end of boot, so only a tiny part of udev informations are there. If any other info is needed, I'll try to provide it.
Can you please install udev-141-5 from:
and start with the kernel command line "udevinfo udevlog"
then you can attach the file /dev/.udev/udev.log which should contain a complete log.

Packed udev.log, because unpacked weights nearly 700kb.
It might be, that this takes so long.. Can you try it?
# time create_floppy_devices -c -t -m 2 -M 0640 -G floppy /dev/fd0
Do you have your floppy enabled in the BIOS and no real floppy drive?
ah, should be:
# time /lib/udev/create_floppy_devices -c -t -m 2 -M 0640 -G floppy /dev/fd0
Corrected command was also wrong - `-t' didn't have an argument. Anyway, command executed quickly:
[kudi@fiodor ~]$ time /lib/udev/create_floppy_devices -c -t 2 -m 2 -M 0640 -G gloppy /dev/fd0
My computer is laptop - Dell Latitude C610 (probably about 6 years old). I don't have any floppy drives installed and BIOS also tells me so.
Hmm, it seems that your BIOS reports a floppy...
 util_run_program: '/sbin/modprobe -b acpi:PNP0700:'
You can check it with:
# find /sys -name modalias | xargs grep -l PNP0700
Workaround for your buggy BIOS:
# echo "blacklist floppy" > /etc/modprobe.d/blacklist-floppy.conf
Hope this resolves the issue.
Yes, now it loads quickly as it should. Thanks for help!
(Strange that udev was sensitive to my buggy BIOS now, not earlier.)
well, I fixed floppy autoloading in the new version :)
