Re: [Crash-utility] crash version 4.0-4.4 is available
Hi,
* Dave Anderson <anderson(a)redhat.com> [2007-07-20 21:42]:
- Implemented support for the use of "kerntypes" debuginfo files that
are created by the LKCD "dwarfextract" utility, as an alternative to
the use of the vmlinux file. This requires the use of the matching
System.map file, as in this example:
# crash kerntypes System.map [vmcore]
This capability was written by Cliff Wickman of SGI, and he has
generously offered to maintain its functionality. (cpw(a)sgi.com)
Hm ..., I like the feature, but it doesn't work here (x86_64,
2.6.22.1). I just compiled the kernel with debugging information (-g),
then
dwarfextract -p -s vmlinux Kerntypes
and now
crash -s /boot/System.map-2.6.22.1-default Kerntypes
WARNING: cannot determine pgdat list for this kernel/architecture
crash> p jiffies
p: gdb request failed: p jiffies
Am I doing sth. wrong here? With
crash -s /boot/System.map-2.6.22.1-default vmlinux
everything works flawlessly.
Thanks,
Bernhard
PS: I compiled dwarfextract with the patches from lkcdutils
(https://lkcd.svn.sourceforge.net/svnroot/lkcd/trunk/lkcdutils/PATCHES/)
applied to libdwarf from http://reality.sgiweb.org/davea/dwarf.html
(latest version).
