Description Krzesimir Nowak 2009-07-13 19:07:00 EDT
Created attachment 351534 [details] boot.log 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 - 188.8.131.52-191.fc11 How reproducible: By booting. Steps to Reproduce: 1. Boot. 2. 3. Actual results: Udev loads too long. Expected results: Udev loads quickly. Additional info: 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: https://koji.fedoraproject.org/koji/buildinfo?buildID=114226 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.

Created attachment 351580 [details] udev.log Packed udev.log, because unpacked weights nearly 700kb.
Comment 3 Harald Hoyer 2009-07-14 09:05:18 EDT
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?
Comment 4 Harald Hoyer 2009-07-14 09:09:44 EDT
ah, should be: # time /lib/udev/create_floppy_devices -c -t -m 2 -M 0640 -G floppy /dev/fd0
Comment 5 Krzesimir Nowak 2009-07-14 09:49:54 EDT
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 real 0m0.154s user 0m0.056s sys 0m0.010s 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.
Comment 6 Harald Hoyer 2009-07-14 10:25:44 EDT
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
Comment 7 Harald Hoyer 2009-07-14 10:26:07 EDT
Hope this resolves the issue.
Comment 8 Krzesimir Nowak 2009-07-14 13:05:51 EDT
Yes, now it loads quickly as it should. Thanks for help! (Strange that udev was sensitive to my buggy BIOS now, not earlier.)
Comment 9 Harald Hoyer 2009-07-15 02:35:37 EDT
well, I fixed floppy autoloading in the new version :)
