Created attachment 140814 [details] [review] Do posting read in psp_v10_0_cmd_submit
Does this patch help by any chance?
No, unfortunately it does not change the times.

Also, I wonder why the sleep in the trace is 3 ms instead of 1 ms like in the code.
Maybe your kernel is configured with CONFIG_HZ=300? Anyway, it doesn't really matter, as it's waiting for the PSP to finish processing the command.
``` $ grep CONFIG_HZ .config # CONFIG_HZ_PERIODIC is not set # CONFIG_HZ_100 is not set # CONFIG_HZ_250 is not set # CONFIG_HZ_300 is not set CONFIG_HZ_1000=y CONFIG_HZ=1000 ```
