Description of problem:

Attempt a static IP installation (rawhide/i386)

Version-Release number of selected component (if applicable):
anaconda-11.5.0.38

How reproducible:


Steps to Reproduce:
1. Enter static IP details
2. Enter URL of http://download.fedora.redhat.com/pub/fedora/linux/development/i386/os
3. When it fails to find i386, click Back
4. At lang screen, select Next
  
Actual results:

See attached image ... segfault

 * Should "Back" in step#3 take me to lang selection for the network config screen?

Expected results:

 * static IP should work
 * no segfault when navigating Back/Next through loader prompts

Additional info:
Comment 1 Chris Lumens 2009-03-27 17:27:45 UTC 
eu-addr2line tells me that 0x805229e is loader.c:1386, which is this:

class = installMethods[validMethods[loaderData->method]].type

I'm going to take a wild guess here that loaderData->method is invalid.
Comment 2 James Laska 2009-05-11 19:53:12 UTC 
Setting fedora_requires_release_note to document the behavior that when entering a static IP, should the server and path entered not be valid, there is a potential interaction bug when navigating Back to the installation method screen.  This bug will manifest as a segfault.  The work around is to reboot the system using a valid server and path.
Comment 3 Bill Nottingham 2009-05-15 20:19:20 UTC 
If this is only in the fallback case on bad input, is it truly a release blocker?
Comment 4 James Laska 2009-05-18 11:23:59 UTC 
Bill: I've set the fedora_requires_release_note? to document this behavior in the Fedora 11 release notes.  

Unless the fix is simple+straightforward, I suspect playing with loader at this stage would not be wise.  Chris, should we keep this on bug#F11AnacondaBlocker ?
Comment 5 James Laska 2009-05-28 12:36:29 UTC 
Retesting against anaconda-11.5.0.55 and I'm not able to reproduce.  Perhaps this is related to the uninitialized memory issue that notting addressed (bug#501757)?  Or something may still be lurking.
Comment 6 Bug Zapper 2009-06-09 12:44:10 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Closing on the basis of comment #5.  If we see this again, we can open it back up.
