It's yet unknown whether recent BIOS fixes the problem. Blacklist regardless of BIOS revisions for now. Sandor Bodo-Merle reported and provided the initial patch for this issue. Signed-off-by: Tejun Heo Reported-by: Sandor Bodo-Merle Cc: Shane Huang --- Sandor, sorry that I ended up redoing this series but without proper dmi_get_date() it was too ugly. Your second patch was fine but it just didn't look right with the manual date parsing callback.
