Red Hat Bugzilla – Bug 242256
2.6.21-1.3194.fc7 fails to boot
Last modified: 2008-08-02 19:40:35 EDT
Description of problem:
It has been discussed extensively on Fedora Forum, but developers continue to
ignore the problems because no bug report get through and approved
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum upgrade
endless loop trying to load drive
as with the last version that has worked for me .3175, a normal startup
Problem appeared with .3189 and has persisted
probably a dupe of 241249
can you try some of the workarounds listed there?
No, I don't think it is a dupe of 241249. It probably is a dupe of some other
bug report that I have been unable to find relative to all of the problems that
people are reporting on Fedora Forum about usb drives.
I say that for two reasons:
1) I tried clocksource=acpi_pm , that is, I appended the statement before
booting .3194, it made no difference. I didn't try the other suggested
workarounds because they seem specific to dual core problems and seemed less of
a solution for some who tried them.
2) The reporting during the boot, similar to problems with earlier kernel
versions after .3175 which works for me, is "usb 2-1 configuration #2 chosen
from 1 choice"
There is an F7 kernel-update candidate available here:
Which contains various fixes maybe this fixes your problem too, please try this
kernel and report back how it works for you.
Always be carefull when testing new kernels. Use rpm -ivh to install the new
kernel besides your current one so that you can always boot back into the old
Yes, I try to be careful although I lost .3175 and it took an extensive search
to find it, again.
Of course, if one uses yum, then it wipes out the older kernel, (the one that
works) for two consecutive ones that don't.
But thanks for the caution.
Same problem with .3226 as with .3194, (was there a .3190?) and .3189
To wit, SCSI Device: sda yadda yadda enabled yadda disabled yadda yadda doesn't
support DPO or FUA
Whereas shut off (not restart because for some reason choosing the working kernel
doesn't matter with a restart, it has to be a cold boot) then reboot with .3175,
which works and the cryptic message that a kernel guru might understand saying
"Attached SCSI Disk sda"
Gawd knows what the diff is, I surely don't
Similar problem with .3228 as with most recent series. Freezes. Requires cold boot to
get back to working kernel.
Thankfully, I had deleted the prior non-working kernel, so that my working kernel was
not removed by the yum update.
Is it simply a matter that the older kernel waits while the new ones do not?
can you make sure you have the latest mkinitrd update installed, and then
recreate the initrd for the latest kernel you have installed.
(run mkinitrd as root for example usage, or you can just rpm -e the kernel, and
reinstall it, and it'll recreate it for you).
I gave up and installed Ubuntu 6.06-LTS.
Disappointing since I had used Redhat / Fedora since rh-7.3.
I did install fc-7 on a VMware appliance on a different machine
to track progress, but figured that there was a rule out old machines
since the money is with rich RHEL business customers and
Fedora developers that need not worry about architecture. Stopped
hoping that I could use the same machine on which I always had
Better to close this out, rather than reminding me further of the
