Read Disk does a modification of ExtMbrStartingLba with the code MultU64x32 (ExtMbrStartingLba, BlockSize) Error detection to see if ExtMbrStartingLBA has a value of 0. This is invalid as LBA 0 = MBR. After modification, the next time ExtMbrStartingLba is in this function if ExtMbrStartingLba is set to 0 in the MBR it never passes the while/do evaluation It is multiplied by 0 by read disk , set to 0 by an invalid MBR and goes back to evaluation This condition will also cause Ws19 and WS22 to hang, however Microsoft has developed a hotfix patch that will be released in 2022 Cc: Liming Gao <gaoliming@byosoft.com.cn> Cc: Jian J Wang <jian.j.wang@intel.com> Cc: Hao A Wu <hao.a.wu@intel.com> Cc: Ray Ni <ray.ni@intel.com> Cc: Zhichao Gao <zhichao.gao@intel.com> Signed-off-by: Craig Edwards <craig.edwards@dell.com> Reviewed-by: Hao A Wu <hao.a.wu@intel.com> |
