I have been wondering why I kept seeing drives activated twice during system resume since this got added. It seems that the EH process can run up to 5 times as long as there is still pending EH. I am not sure why, but it look like my Intel AHCI controller issues an error interrupt during the first round of EH, even though there does not appear to be any error. This causes the EH_PENDING flag to be set again, and so a second round of EH happens, which then tries to activate the disk a second time. I propose the following patch to only set the ACTIVE flag once.
