Description Mark McLoughlin 2008-03-18 12:03:54 UTC 
For bug #436485, we had to change our kernel config as follows:

  -CONFIG_PHYSICAL_START=0x1000000
  +CONFIG_PHYSICAL_START=0x200000

  -CONFIG_SPARSEMEM_VMEMMAP=y
  +# CONFIG_SPARSEMEM_VMEMMAP is not set

This indicates something broken with the x86_64 support which we should be
looking to fix and the change the config back to match the stock config.
Comment 1 Mark McLoughlin 2008-03-18 19:07:03 UTC 
Also need to re-enable:

  - CONFIG_SMP
  - CONFIG_NUMA
  - CONFIG_IA32_EMULATION
Comment 2 Mark McLoughlin 2008-04-15 15:40:15 UTC 
Punting to F10
Comment 3 Bug Zapper 2008-05-14 06:40:48 UTC 
Changing version to '9' as part of upcoming Fedora 9 GA.

Comment 4 Mark McLoughlin 2008-05-29 16:45:41 UTC 
CONFIG_IA32_EMULATION is re-enabled, so we're left with:

# CONFIG_SMP is not set
# CONFIG_NUMA is not set
# CONFIG_NEED_MULTIPLE_NODES is not set
CONFIG_PHYSICAL_START=0x200000
# CONFIG_SPARSEMEM_VMEMMAP is not set
Comment 5 Mark McLoughlin 2008-07-21 15:42:14 UTC 
Okay, with kernel-xen-2.6.27-0.2.rc0.git6.fc10.x86_64 all of these have gone
back to the stock configuration
