Description Wade Mealing 2009-02-10 02:05:31 UTC
Description of problem:

After having a panic, or by forcing one, the kdump kernel boots and is stuck after attempting to detect/classify memory.

After rebooting and building a new kdumprd, then rebooting again
       1: The kdump kernel doesn't start up if fibre is disconnected.
       2: Nor does it work if the fibre cards are unplugged.  
       3: Nor does it work if the ethernet cards are unplugged. 

System seems to hang at the same point in the boot, screenshot to be attached.

Version-Release number of selected component (if applicable):

initrd-2.6.18-120 with hotfix from bz470074

How reproducible:

Every time

Additional info:

Regular kernel seems to boot fine. Screenshot to be attached.  I dont have the kdump skills to debug this properly.

what is initrd-2.6.18-120?

What version of kexec and kernel are you running?  whats your kdump.conf look like?  what kind of system is this?  Can you attach a sysreport?

Comment 6 Wade Mealing 2009-02-23 02:18:03 UTC
Update:

The system seems to hang there, regardless of the state of the ethernet devices or the fiber connections. 

Kdump configs attached.

This is a dupe of 462519, pretty clearly.
