Public bug reported:
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)
