@mnowak: any idea?

I don't know of anything we could do, especially in 'openQA tests'. VNC_TYPING_LIMIT is already at 10... I am afraid VNC won't let us do it a smarter way.

that is strange, https://openqa.suse.de/tests/1261746#step/yast2_bootloader/8 shows exactly the same key lost as mentioned in #26014#note-4 . I don't think this is a "random key lost" issue, it's a specific one. @michalnowak any idea why the "r" of "bootloade*r*" is not correctly typed/forwarded? Seems this problem appears in the same character but also not in every job? Might just be a very strange coincidence though but why again the same test module then?

Also in https://openqa.suse.de/tests/1261812#step/yast2_bootloader/8 , this can't be a coincidence.

The original problem https://openqa.suse.de/tests/1236180#step/yast2_bootloader/5 is a different to https://openqa.suse.de/tests/1261812#step/yast2_bootloader/8. In the former one key on VNC screen is not present, on the latter one a letter did not make it via serial console.
But the latter thing you mention is certainly not a coincidence. The string is not making it quite reliably (I've seen it in the past), interestingly it's a always a 16th character... We are lucky script_run control strings are shorter. I wonder if some combination of baud rate and parity checking could (https://github.com/torvalds/linux/blob/master/Documentation/admin-guide/kernel-parameters.txt#L603) make a difference here.

Simple workaround would be to shorten the magic control string yast2-bootloader-status-$? to about 8 characters... if anyone feels it's sensible solution for now. (Can't look into it in next ~10 days myself, though.)

PR merged, the next job https://openqa.suse.de/tests/1311517 was ok but we need more statistics. That worker is quite loaded so I did not trigger a whole bunch of tests to gather statistics. I guess we should just wait.

with https://openqa.suse.de/tests/1317255#step/yast2_bootloader/8 passed as well I think we are good now. We could keep the ticket open because we just applied workarounds but will we ever be able to fix it? Maybe. If that is the case then we can still apply the changes but let's close this ticket for now.
