Description Wade Mealing 2006-06-22 14:45:00 UTC
Description of problem:

Burned boot.iso from the images directory to a CDRW, booted, selected "http"
install method, see nasty messages on blue anaconda screen, exits with signal 6,
and best of all, i can now safely reboot my system.

-> no wierd messages on 4th vt.
-> fc5 installed fine

If this is a dupe, I can't find the original, if more information is required, i
can setup a serial console tommorow in the office and get the exact messages.

We've fixed a number of these... do these still occur with 0625 or later?

Comment 5 Matthias Saou 2006-06-26 14:50:32 UTC
I'm seeing this with 0626 i386 boot.iso trying to do a network install under
qemu (both ftp and http).

Comment 6 John Reiser 2006-06-27 02:33:02 UTC
I see this on PowerPC (Apple Macintosh model M8570, PowerMac G4 1GHz "silver
drive doors" circa 2003)

I used
FC-development-ppc-rescuecd.iso	2006-Jun-25 23:43:00	98.7M	application/octet-stream
with md5sum 1b7f0c7e1fe381ee40c117cbd49bfbcd.  I booted "linux askmethod", HTTP,
fedora.cat.pdx.edu , linux/core/development/ppc/os/Fedora .  Then:

*** glibc detected *** /sbin/loader: double free or corruption (fasttop): 0x104b4930

Comment 7 Tom Horsley 2006-06-27 16:36:00 UTC
I wonder if bug 196419 is the same problem? (I see the same kind
of heap errors once I captured the console output, but in a different
program: /sbin/kpartx for me, and more important my 2nd drive
won't talk to me).
