Any one found handy using WPA/WPA2 PMK mode (2501)? Does it actually speed up crackkng process? Please share you experience compared with 2500 mode.

Oh, just noticed it is no longer supported by hashcat. Odd...

Here is some information I have found:
"We can speed this up by pre-calculating the Pre-Shared Key, also called the Pairwise Master Key (PMK) in the 802.11 standard parlance. It is important to note that, as the SSID is also used to calculate the PMK, with the same passphrase but a different SSID, we would end up with a different PMK. Thus, the PMK depends on both the passphrase and the SSID."

This mode was designed to speed up cracking hashes by pre-calculating PMK for given SSID and a list of pass phrases, so then can be used along with dictionary that will run quicker.

Anyone can advise, please, on this subject?

genpmk (PMK generator) is still can be found in Kali Linux and can be used along with cowpatty to wpa/wpa2, but I doubt cowpatty support GPU usage.

I wonder if the PW can be found by combining the PMK and Handshake Hashes.

No, there is no way of using both together to find PW
If you have both, better to use PMKID

Pmkid cracking is not faster than cracking the handshake (they both seem to run at the same speed), the only three advantages that i have encountered is,
no need for a station on the network to get a handshake,getting a pmkid is superfast almost instant. the pmkid is clean, no crap to clean up. I prefer PMKID than a handshake.
