Title: S11 not mining
Post by: sfmolavi on August 27, 2020, 07:45:54 PM

hi. none of the boards of s11 are hashing. and this is end of its kernellog

Code:

get RT hashrate from Chain[0]: (asic index start from 1-84)
Asic[01]=0.00000 Asic[02]=0.00000 Asic[03]=0.00000 Asic[04]=0.00000 
get RT hashrate from Chain[1]: (asic index start from 1-84)

get RT hashrate from Chain[2]: (asic index start from 1-84)
Check Chain[J1] ASIC RT error: (asic index start from 1-84)
Check Chain[J2] ASIC RT error: (asic index start from 1-84)
Check Chain[J3] ASIC RT error: (asic index start from 1-84)
Done check_asic_reg
read failed on Chain[0] Chip[18] middle Temp old value:15
Special fix Chain[0] Chip[18] middle Temp = 15
read failed on Chain[0] Chip[34] middle Temp old value:15
Special fix Chain[0] Chip[34] middle Temp = 15
Done read temp on Chain[0]
Done read temp on Chain[1]
Done read temp on Chain[2]
Max pcb temp : 0
FAN PWM: 40
read_temp_func Done!

At first glance it looks like temp sensor failure or PSU. But I could be wrong as I do not see full Kernel Log.

I need to see the following:

1- Miner status page (screenshot), use this website https://imgur.com/ to upload the image.
2- I need to see a complete kernel log, use the code function as explained by favebook.
3- Readings of the AC voltage.

With the above information, I might be able to help you troubleshoot the miner.

It seems that the miner is overheating that's why it shows abnormal temp.

It would be better if you can share it with us the full kernel logs as suggested above.

According to partial logs above it seems that the fan is set at low speed "FAN PWM: 40" and it seems that the miner is overheating that's why it shows abnormal temp I guess.

If you don't have extra power supply try to run the miner at low power mode.

You can find it on "miner configuration" at the bottom under work mode.

I don't think so, no where in the kernel log where it mentions anything about overheating, it isn't possible because the miner only starts mining after this stage

Code:

read_temp_func Done!

Whatever happens before is just testing the temp-sensors to see if they are reporting valid readings, the temps in the kernel log imply that the sensor readings aren't accurate and that's due to a bad PSU or dead Asics on certain hashboards, but without seeing the complete kernel log and all the other details we requested, all we can do is speculate.

hi,tnx for answering my question. i cant send all part of kernel log because its more than 640000 word. could u plz help me to upload kernellog?

i changed fan and PSU but nothing didnt change.now i cant send all part of kernellog because its more than 64000 charecters.

You can upload them in separate parts on different posts, alternatively, you can use something like https://justpaste.it and post the like there and then copy-paste the URL.

Also upload the miner status page, pool settings using one of these websites https://imgbb.com/ or https://imgur.com/ ( you can hide a part of it for privacy).
