Priority: medium Bug ID: 81896 Assignee: dri-devel@lists.freedesktop.org Summary: GPU reset when running some "John the Ripper" (+ jumbo patch, from Git) OpenCL tests Severity: normal Classification: Unclassified OS: Linux (All) Reporter: lbdkmjdf@sharklasers.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
Created attachment 103669 --> https://bugs.freedesktop.org/attachment.cgi?id=103669&action=edit mixed outputs
I get GPU reset when running some opencl tests from this program from TTY. If I'm running a DE when the lockup happens, the system stops responding. Attached are: - the mixed output from /var/log/syslog and this command: $ R600_DEBUG=cs LWS=128 GWS=9216 ./john --test --format=PBKDF2-HMAC-SHA256-opencl
- an attempt to clean it, only leaving the output from "R600_DEBUG=cs"
Also notice, there is random garbage after "Build log:", which comes from clGetProgramBuildInfo ( https://github.com/magnumripper/JohnTheRipper/blob/bleeding-jumbo/src/common... , prints "Build log:" in line 768)
My system: Hardware: HP dv6, CPU: AMD A6-3400M, GPUs: Radeon HD 6520g (evergreen) + 6750M (north islands) OS: Kubuntu 14.04 Kernel: 3.15.7, and 3.13, both amd64 Mesa 10.3~git1407290730.9a53f9 (from oibaf's PPA, https://launchpad.net/~oibaf/+archive/graphics-drivers ), compiled with LLVM 3.5-rc1.
________________ To reproduce, here's a mini "how to run" for "John The Ripper" + "jumbo" patches: $ git clone https://github.com/magnumripper/JohnTheRipper $ cd JohnTheRipper/src $ ./configure && make $ cd ../run $ ./john --help # prints usage help $ # the following command prints a list of hash format tests that use opencl, separated by spaces. remove the awk part to get one per line: $ ./john --help | grep -Eo '[a-zA-Z0-9-]*-opencl' | awk '{printf "%s ", $0}'; echo
To run a test: $ ./john --test --format=$format where $format is one of the formats listed from the previous command
The program does verify the output. When it fails, it should print something like "FAILED (get_hash[0](0))".
