Hi,
I've a problem with an image from a Microsoft Surface tablet.
I've verified that the OS is Windows 10 Pro 64Bit, and "imageinfo" confirms
that:
Suggested Profile(s) : Win10x64
AS Layer1 : AMD64PagedMemory (Kernel AS)
AS Layer2 : FileAddressSpace (/srv/evidence/memdump.mem)
PAE type : No PAE
DTB : 0x1ab000L
KUSER_SHARED_DATA : 0xfffff78000000000L
Image date and time : 2016-06-16 12:52:11 CEST+0200
Image local date and time : 2016-06-16 12:52:11 +0200
However, all comands take hours to complete, imageinfo took about an hour,
kdbgscan was closer to 10 hours (I let it run through the night).
$ ./vol.py --tz=CET --profile=Win10x64 -f /srv/evidence//memdump.mem kdbgscan

I think the later part is the right one, but when I run pslist with the value
for
KdCopyDataBlock, I get something like this, using other options/values simply
gives
empty output.

I can't say wether the addresses and pids (the first two ones look bad) are
correct, but the process name field surely does not look good. Any ideas?
