While this question was not directed at me, I indeed find that bit 3 of the leftmost byte is set with 2.6.24:
# hexdump -s 0xc0010015 -n 8 -C /dev/cpu/0/msr c0010015 18 00 00 01 00 00 00 00 |........| c001001d # uname -a Linux quad 2.6.24.4-default #1 SMP Mon Mar 31 18:51:48 BST 2008 x86_64 x86_64 x86_64 GNU/Linux
while (as expected) it was zero running 2.6.23.17 patched with the erratum 298 workaround. Yet I saw the lockups with both kernels.
Thanks, Tim
