Thanks, I had a good laugh here

Unfortunately, I don't have 13 p104 cards to test it. So 12 cards work fine and 13 fail, right? There is no difference for miner if you use 12 or 13 cards so it must be something else, try "-gser 2" option to see if it helps.

hmm, yes. 12 cards are working. you definitely do not like this number)
and 13 with with -gser 2 option, too. but very slow startup.
with -gser 1 does not. and I found in syslog this

Code:

[27382.925779] Out of memory: Kill process 10880 (ethdcrminer64) score 684 or sacrifice child
[27382.925822] Killed process 10880 (ethdcrminer64) total-vm:321404352kB, anon-rss:1346268kB, file-rss:1308172kB, shmem-rss:133120kB
[27382.948105] oom_reaper: reaped process 10880 (ethdcrminer64), now anon-rss:0kB, file-rss:1313400kB, shmem-rss:133120kB

sorry, forgot to take a look there earlier
hope this help to trace the problem
v11.9 also works without -gser.

It seems drivers are unstable at this number of cards.
If 11.9 works fine you can try to add "-eres 2" option, miner will use old-style DAG generation (since v12 it tries to reduce GPU memory used for DAG in most cases, non-zero "-eres" option value disables it).
