I found that after CPU offline test, I can't read/write SD card. After checking dmesg, I got those error msgs. [ 232.577510] __common_interrupt: 7.34 No irq handler for vector [ 234.354327] mmc0: error -110 doing runtime resume I found the same issue on Dell Precision 3551(202002-27718) and Dell Precision 5530(201807-26342) in 5.13.0-21 and 5.11.0-36 Before I didn't think it's a bug since I re-run mediacard test then it's pass. But this cycle there are more systems failed to the test, I just started digging into that. [Step to reproduce] 1. install ubuntu-20.04.2/ubuntu-21.10/ubuntu-21.04 2. sudo apt update; sudo apt dist-upgrade -y 3. run cpu offline test via checkbox-cli or execute following command for ((i=1;i<=$(nproc --all) -1;i++));do sudo chcpu -d $i;sudo chcpu -e $i; done; cd $mount_point_of_sd_card sudo dd if=/dev/urandom of=test bs=1M count=10 [Expected result] Can read/write SD card. [Actual result] Can't read/write SD card.
