Gigabyte GA-MA69VM-S2 can't do 64bit DMA either. 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 <tj@xxxxxxxxxx> Reported-by: Sandor Bodo-Merle <sbodomerle@xxxxxxxxx> Cc: Shane Huang <shane.huang@xxxxxxx> --- 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.
