Therefore, x86 + Asmedia3042 cannot be verified. I conducted the test using x86 + uPD720201, and the issue was not reproduced. 在 2026/7/31 18:57, Michal Pecio 写道: > On Fri, 31 Jul 2026 15:38:22 +0800, Jie Deng wrote: >> The S3 test script is as follows: >> #! /bin/bash >> # >> for i in $(seq 1 $1); do >>     echo "the $i th s3" > /dev/ttyAMA0 >>     echo "the $i th s3" >>     rtcwake -m mem -s 20 >>     sleep 15 >> done > That's simple enough, I could run it for a few hours on x86 PC with > a few different PCIe xHCI cards. > > Just in case, are some USB devices supposed to be connected, or not > connected, or maybe it's known to make no difference?
