Description Alan Mead 2005-05-22 01:01:50 EDT
Description of problem:

Ran up2date tonight to update my working, stock FC3 i386 distribution.  The
kernel was updated from 2.6.9-1.667 to 2.6.11-1.14_FC3.

Now I get a kernel panic during boot.

Red Hat nash version 4.1.18 starting
Kernel panic - not syncing: drivers/ide/pci/piix.c:231: 
   spin_lock(drivers/ide/ide.c:c036dc408) already locked by 
   drivers/ide-iops.c/1153.  (Not tainted)

How reproducible:
Steps to Reproduce:
I haven't re-installed FC3 but the kernel panic happens each time I boot.
 

Additional info:
I can supply additional information about the hardware.  It's an old (cerca
1998) whitebox that has run FC3 fine until now.

Can you try the kernel at http://people.redhat.com/davej/kernels/Fedora/FC3/
and see if that fixes this ?
Comment 2 Alan Mead 2005-05-22 01:47:32 EDT
I could try a new kernel if I could figure out how to mount / rw (or... why when
it is mounted rw I cannot make any changes to it).  Here is some information
from the dmesg after booting 2.6.9-1.667 ... I guess I was having problems all
along it:

EXT3-fs: mounted filesystem with ordered data mode.

To my untrained eye, that appears to be a dying hard disk.

The spinlock bug is fixed in the update that went live this morning.
