Subject: makedumpfile fails on SGI machine
Date: Wed, 30 Jul 2008 16:14:16 +0200 [thread overview]
Message-ID: <20080730161416.47605c30@halley.suse.de> (raw)
Hi,
makedumpfile 1.2.7 fails on a SGI machine with following error:
readmem: Can't convert a virtual address(a0007fff8f900000) to offset.

--------------------------------------- >8 --------------------------
After debugging that, I didn't find an error code. That address is in
fact the beginning of the mem_map of that node, and is in fact not
mapped (I verified that in crash).
With an older kernel and an older makedumpfile it succeeds. The
debugging output here is:
