I am seeing reboot upon GETSEC[SENTER], and I am pretty much out of ideas on how to diagnose or work around the problem. I'm looking for help or ideas of where to go from here. This is on an i5-2500 platform with Q67 chipset. I'm using tboot 1.7.4 and 3rd_gen_i5_i7_SINIT_67.BIN (even though the main intel page says I should use the 2nd gen SINIT, most other sources, even those from intel, say that the 3rd gen is backwards compatible and the 2nd gen SINIT is "revoked").
I get this error code:
TBOOT: TXT.ERRORCODE: 0xc0002851
TBOOT: AC module error : acm_type=0x1, progress=0x05, error=0xa
The table says 0x05="chipset configuration" and 0xa="Invalid ILP SMRR configuration"
I updated bios from A06 to A11, with no change. I haven't been successful updating to bios A19.
I can find almost no documentation whatsoever about the SMRR register. I get the same error with or without a LC policy in place. The 2nd gen SINIT doesn't reboot in this same way, instead it simply freezes at GETSEC[SENTER}, requiring me to do a cold reboot and losing any stored TXT.ERRORCODE.
