Note that 4.1 is not officially released yet. You installed a release candidate, which is not suitable to be used as a daily driver, it’s purpose is testing. By telling us what doesn’t work, you help the Qubes team to fix the bugs and regressions. See also: Joining the Testing Team.

not normal at all. anything suspicious in dmesg?

sudo dmesg?

so this is so complex what parts copy and send to u?

watch for any repeated lines. this behavior is typical for overloaded kernel log system
