Weird black screen during extensive disk i/o testing | NovaCustom | V560TU
Component
Dasharo firmware
Device
NovaCustom V54 14th Gen
Dasharo version
v0.9.0
Dasharo Tools Suite version
Test case ID
disk-io suite (wip)
Brief summary
during testing of the automated disk performance tests an issue emerged involving the laptop to appear powered on and yet the screen was black.
How reproducible
it is really likely to stumble upon it when running the test (99%)
How to reproduce
run the disk-io suite from this commit: https://github.com/Dasharo/open-source-firmware-validation/pull/719/commits/1fb4f9d4f5761aa49d06881d1a60aef88f9be835
Expected behavior
the laptop shouldn't go into such state i guess
Actual behavior
the laptop enters a state in which the LEDs on power button and the front of the laptop stay lit while the screen is black, no inital response after pressing any key or power button
Screenshots
No response
Additional context
in this black screen state when trying to press any keyboard button or power button (short time) the computer is not responding for few minutes and then it starts working again (~7min) as if it was on some kind of strong suspend.
Log of one of my runs that also includes the wake up after few minutes. The issue occured during 2nd test case and the platform woke up before 4th test case
Solutions you've tried
the laptop needs some time to turn back on again, initialy leading me to believe the only way out of this situation was a restart by cutting of power
Adding sleep kwd between tests is a reliable method to fight this issue:
@wiktormowinski does the laptop enter this sleep state on its own, without any action in the tests?
@mkopec no, i think i only saw this kind of behavior triggered by something within the tests
does this still happen on the latest RC and on the latest version of the tests?
@mkopec just checked it
doesnt occur on latest rc2, V540TU
even removed the 20s Sleep kwds that were supposed to prevent this issue, still no reproduction.
However, this test is disk dependant, perhaps the disk model is different on each asset
Also I've just noticed that the indexes are wrong .202 and .201 are entirely different (i was unaware of it during development)

Thus:
- though i was unable to reproduce this on 00122(has SSDPR-PX700-01T-80) asset, I think the issue can still be spotted on a different disk
- IDs should be changed (osfv related)
- the
Sleep 20skeywords can also be removed if no reproduction
this problem is similar to this issue: https://github.com/Dasharo/dasharo-issues/issues/1456
