Hi,
We are experiencing persistent I/O request timeouts on Linux with P3520/P4600 SSDs. We have tried multiple different kernels (3.10, 4.4, 4.9) and see the timeouts on all of them. The P4600 seems to be more prone to these than the P3520 though we see them on the latter as well. We have the latest firmware installed on both drives which are housed in the same machine (Supermicro 5018R-WR with X10SRW-F motherboard and E5-1650 V4 CPU). We can reproduce the timeouts by simply running mkfs -t xfs on the drive.
Here is the output from isdct (version isdct-3.0.9.400-17.x86_64):

Here are the messages the 4.9 kernel prints when using the P4600
