Hi,
Unfortunately, the mac is still crashing randomly after a few days.... This is what I get in the report :
panic(cpu 0 caller 0xffffff80203d5f07): "com_apple_driver_AppleUSBCardReaderDriverNub::setPowerState(0xffffff936fba4000 : 0xffffff8021396074, 1 -> 2) timed out after 30380 ms"@/System/Volumes/Data/SWE/macOS/BuildRoots/2288acc43c/Library/Caches/com.apple.xbs/Sources/xnu/xnu-7195.101.2/iokit/Kernel/IOServicePM.cpp:5382
