Topic name might be a bit inaccurate. It is hard to tell me if it cracks or not like 2-3 days ago I was able to crack 14k hashes out of 21k (21 mode). Now I tried to crack simple IPB hash which contained simple password, that was in my wordlist and I did not get any result it happend to me twice (yesterday and today) with two different IPB hashes. I tried to crack it with old oclHashcat-2.01 and it managed to do it with exactly the same wordlist. I would appreciate any advice.
Could you provide the command you used (with the hash itself censored)?
Please provide anything (hash, wordlist, commandline, etc) for devs to reproduce this and to ensure it's not a bug, but from 9 of 10 of those cases it's just an invalid OpenCL installation.
hashcat64.exe -m 2811 -o cracked.txt hash.txt wordlists
This is command I used. Example of wordlist I used is 0...9999999.txt (contains all numbers 0-9999999) it should find this hash: 27f47fb8a143fdb286605901a29c361e:1K,R<:2112002 (I hope I am allowed to post already cracked hash) because wordlist contains it. Someone on the forum, the hash been posted, cracked it and that made me realise something is wrong with my hashcat.
Works fine, see here:

ATTENTION!
The wordlist or mask you are using is too small.
Therefore, hashcat is unable to utilize the full parallelization power of your device(s).
The cracking speed will drop.

As I said, it's propably your OpenCL installation.
