Hi, Thank you for reporting it. Could you please try to update the firmware of the monitor and laptop, boltd, and RHEL kernel to see if the issue still appears? Thank you
Hi, currently this problem is not happening anymore for me. I dont know at which point it started working but only think i have done since then is OS update.
Hi, Great to hear that. The usci issues of kernel, such as NULL pointer, race condition, and canceling a queued command were got fixed. I believe the issues you reported were fixed through those patches. Now, the system works properly and this bug could be closed. Would you mind me closing the issue or do you want to close it yourself? Thank you
Closing this issue as it is not happening anymore and most likely was fixed in previous updates, see comments above.
