Hello I installed hashcat on a
Code:

#lspci -s 00:2
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)


And get first something about Intel's OpenCL runtime being broken (which I don't know if its true)
Code:
$ hashcat -m 2500 net.hccapx rockyou.txt 
hashcat (v5.1.0) starting...

* Device #1: Intel's OpenCL runtime (GPU only) is currently broken.
             We are waiting for updated OpenCL drivers from Intel.
             You can use --force to override, but do not report related errors.
No devices found/left.

Using Force it fails the kernel-self-test:
Code:

$ hashcat -m 2500 net.hccapx rockyou.txt  --force
hashcat (v5.1.0) starting...

OpenCL Platform #1: Intel
=========================
* Device #1: Intel(R) HD Graphics Kabylake ULT GT2, 2945/3927 MB allocatable, 24MCU

Hashes: 7 digests; 4 unique digests, 1 unique salts
Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates
Rules: 1

Applicable optimizers:
* Zero-Byte
* Single-Salt
* Slow-Hash-SIMD-LOOP

Minimum password length supported by kernel: 8
Maximum password length supported by kernel: 63

Watchdog: Hardware monitoring interface not found on your system.
Watchdog: Temperature abort trigger disabled.

* Device #1: ATTENTION! OpenCL kernel self-test failed.

Your device driver installation is probably broken.

Aborting session due to kernel self-test failure.

You can use --self-test-disable to override this, but do not report related errors.
