Generating errors


#1

Whether starting zcashd during a text-mode only session or gui desktop session, it's producing output that I've saved here:

http://s000.tinyupload.com/?file_id=02305800445072531865

Of more concern though, during text-mode sessions, these errors are being produced when I run the solveequihash benchmark:

[ 1322.302734] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] ERROR failed to enable link training
[ 1322.311321] [drm:intel_dp_start_link_train [i915_bpo]] ERROR failed to start channel equalization
[ 1322.469883] [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] ERROR CPU pipe A FIFO underrun

Is that output produced by zcashd?


#2

No, this appears to be a video driver problem. Are you sure it isn't coincidence that happened when you started zcashd or the benchmark?

Edit: it could also be a driver problem that is correlated with high CPU and/or memory bandwidth usage.


#3

Tinyupload.com is not showing me your file. Can you put it somewhere else? (I typically use https://defuse.ca/pastebin.htm .)


#4

@daira Thank you for your feedback - and sorry that tinyupload isn't behaving...

I reposted that terminal output here:

#5

Are you referring to this problem: https://github.com/zcash/zcash/issues/894 ? I don't immediately see any other problem with the output.


#6

I can't tell if the output I got was due to the same issue. It just seemed odd to me because previously starting zcashd didn't produce any output.
