Actually, it is
TXT.ERRORCODE: 0xc00040d1
AC module error :
acm_type: 0x1
progress: 0x0d
error: 0x10

which is:
10000 TPM PCR 17 extend failed

This is caused by an early version of the TPM FW. You can get an update from
your OEM (at
http://support.dell.com/support/downloads/download.aspx?c=us&cs=08&l=en&s=bsdr&releaseid=R288913&SystemID=lat_e6410&servicetag=B7B23M1&os=W764&osl=en&deviceid=21505&devlib=0&typecnt=0&vercnt=3&catid=-1&impid=-1&formatcnt=0&libid=66&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=430067
for some systems).
