Repost to include linux-ia64...
I have an IA64 system with 250G memory. I reserved 1024M memory for the
kdump kernel. It worked fine... up to 2.6.23.
Starting 2.6.24-rc1, booting a kdump kernel on the machine has been
failed on OOM. I tried 1280M, but still failed. I threw in 2048M and
then it worked. When OOM happened, it failed on allocating memory
for adding disk /dev/sdb.
I saw two problems here:
1) the memory needed has been bloated since 2.6.23, and
2) the system tried to add disk /dev/sdb through probe on booting
kdump kernel when it is not even in /etc/fstab. I think only
the system disk and the disk where we want to save the vmcore
to should be needed. It would be nice if there is a way to
initialize only the needed disk.
Below is part of the console messages on OOM.
