For recent failures, see https://ci.debian.net/packages/s/stress-ng/testing/amd64/ and https://ci.debian.net/packages/s/stress-ng/testing/i386/. > 2. Does it fail on specific machines? > 3. What CPU model is the machine it fails on? I can't answer these two questions. I suggest to contact the debci maintainers by, for example, joining #debci on OFTC.

Hi Sebastian, thanks for reporting this. Is is OK to ask a few questions as I've never seen this before on a wide range of kit that I test this on. 1. Is this failure repeatable? (I'm not sure how it occurs since there is a SIGSEGV handler for these cases). 2. Does it fail on specific machines? 3. What CPU model is the machine it fails on? I've tried to understand this failure, but so far I'm quite perplexed by it, so maybe it's a CPU specific caching behavior that I have misunderstood. Any assistance with the questions above would be most useful, Regards, Colin On 13/12/2021 21:48, Sebastian Ramacher wrote: Source: stress-ng Version: 0.13.08-1 Severity: important X-Debbugs-Cc: sramac...@debian.org The autopkgtests of stress-ng fail from time to time: | stress-ng: 20:49:12.58 info: [1091] unsuccessful run completed in 0.51s | stress-ng: 20:49:12.58 fail: [1091] cache instance 3 corrupted bogo-ops counter, 2 vs 0 | stress-ng: 20:49:12.58 fail: [1091] cache instance 3 hash error in bogo-ops counter and run flag, 796547380 vs 0 | stress-ng: 20:49:12.58 fail: [1091] metrics-check: stressor metrics corrupted, data is compromised | cache FAILED ... | zlib PASSED | 42 PASSED | 1 FAILED, cache | 0 SKIPPED See https://ci.debian.net/data/autopkgtest/testing/amd64/s/stress-ng/17550292/log.gz for a recent failure Cheers
