cudaHC stops at Kernel exec timeout

[lordofazeroth]

Hello community.

I am trying to decrypt a hash using cudahashcat+.
I am using a 9600 GT, decrypting WPA2 works perfectely.
But I get problems decrypting SHA512 hashes.

cudahashcat+ -m 1800 /root/test.hash /usr/share/wordlists/rockyou.txt
cudaHashcat-plus v0.15 by atom starting...

Hashes: 8 total, 8 unique salts, 8 unique digests
Bitmaps: 8 bits, 256 entries, 0x000000ff mask, 1024 bytes
Rules: 1
Workload: 4 loops, 8 accel
Watchdog: Temperature abort trigger set to 90c
Watchdog: Temperature retain trigger set to 80c
Device #1: 9600 GT, 255MB, 950Mhz, 4MCU
Device #1: WARNING! Kernel exec timeout is not disabled, it might cause you errors of code 702
^C^X^C

Then it just stops. I have to kill it manually, no status with s is working. Same command with normal hashcat works fine.

Here is some output with WPA2:

cudahashcat+ -m 2500 -a3 /root/test.hccap ?l?l?l?l?l?l?l?l

I read there are a few more devices, Kernel. Does this have something to do with it?
