Deleting files on exFAT USB degrades system

[Leonardo Müller]

I was deleting a large amount of files from an exFAT USB pendrive and at 45% of the file deletion, the system became degraded: USB disks were no longer possible to mount or dismount, no new USB devices were detected, systemd-journal and syslog were using 100% CPU on htop each, shutdown, reboot and suspend were disabled, commands using sudo no longer worked.

I was unable to obtain anything meaningful while the error was happening because of how slow the system became. The following line repeated endlessly:

[ 4649.820335] [EXFAT] sector_read: out of range error! (sec = 330029325056)
