Description of problem:
I have updated kernel-2.6.14-1.1653_FC4 using yum.
When I try to boot it freezes in the middle proccess. It looks like it hangs the computer when the kernel try to start cups at booting time.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum update kernel
2. Turn on the computer
3. Select kernel from grub
I just updated 4 servers to 1653_FC4, 3 came up fine, but the 4th is getting a
kernel panic early in the boot, I think because it's failing to mount the root
file system. Going back to the previous kernel 1644_FC4 fixes the problem for
I'm having trouble gathering useful data because there's no log of the boot as
far as I can tell (makes sense, I guess, since the problem occurs before it
mounts the filesystem). I think I'll try forcing a re-install of the 1653_FC4
My system is SMP and has software RAID as well. Another one of my servers is
virtually identical hardware and software, but it's OK.
p.s. My system isn't using cups.
This is definetely a problem "kernel versus CUPS".
I have intalled: cups.i386 1:1.1.23-15.2 installed
Now if I boot the 1653_FC4 without cups enable in level 3 (service
configuration) the kernel boots fine.
But then when I try to start CUPS (service configuration) the machine hangs.
I have a 2 computer WLAN (wireless). This computer has a printer shared (using
samba and CUPS) so I need CUPS to print. I think here there is the real problem:
with the 1653_FC4 kernel CUPS does not start and frezze my computer.
Just in case, my WLAN is a wireless one. I use a CONCEPTRONIC USB CRU device
with drivers from http://rt2x00.sourceforge.net (package rt2570-cvs-2005121511,
P.S. Whith 1644_FC4 kernel, CUPS fail to start on booting but I can start it
when the LAN is running.
do either of you actually have a printer ? If so, what type? (Parallel/usb ?)
The printer is a EPSON 660 connected throuugh the paralallel port to the same
computer with de problem. It works fine with 1644_FC4 kernel. I think the
printer does not have anything to do with de bug.
From my point of view the bug is that the 1653_FC4 kernel is not able to start
CUPS, perhaps because of the share services of the LAN (WLAN) configuration,
and hangs the computer.
My boot kernel panic with 2.6.14-1.1653_FC4 is not related to cups or printing
(neither are installed on this server). I think this is just the wrong place
for my bug, I'm out of here. Maybe, I'll post a new bug for my issue.
I have just updated to kernel-2.6.14-1.1656_FC4 using yum.
Now it boots fine.
CUPS still fails to start at boot time but I can restart it when my wireless LAN
is running, just the same as with 1644 and previous kernels.
I have removed the kernel-2.6.14-1.1653_FC4 (bye!, Â¡Adios!).
It looks like the problem was related with kernel-2.6.14-1.1653_FC4 when start CUPS.

PD: For devices and hardware information, the wireless device CONCEPTRONIC USB
C54RU works fine with rt2570 USB nightly CVS tarball.
