Subject: AMD crash on restore. bug in MTRR restore. 4.0.2-rc2-pre
Date: Wed, 26 Jan 2011 17:18:50 +1100 [thread overview]
Message-ID: <AEC6C66638C05B468B556EA548C1A77D01BB928D@trantor> (raw)
The mtrr save code on my AMD system reads the first MTRR as
0x00000000f0000000,0x000000fff8000800. When it tries to restore in
mtrr_var_range_msr_set, 0x000000fff8000800 is rejected as invalid and
not restored.
Commenting out the check against the mask, as well as Tim's patch to fix
the segment registers makes the output of xen-hvmctx match before the
save and after the restore.
Windows still crashes on restore though so I don't know if this has
anything to do with it.
James
