Same here, so it is probably normal: $ cat /sys/devices/platform/serial8250/tty/ttyS*/power/autosuspend_delay_ms cat: /sys/devices/platform/serial8250/tty/ttyS0/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS10/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS11/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS12/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS13/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS14/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS15/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS16/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS17/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS18/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS19/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS1/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS20/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS21/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS22/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS23/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS24/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS25/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS26/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS27/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS28/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS29/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS2/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS30/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS31/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS3/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS4/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS5/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS6/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS7/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS8/power/autosuspend_delay_ms: Input/output error cat: /sys/devices/platform/serial8250/tty/ttyS9/power/autosuspend_delay_ms: Input/output error /sys is a pseudo file system.

If so, just boot the kernel you want and remove the newer kernels (using the package manager).
[Trisquel-users] Re : Disconnection from network after waking computer from sleep
I assume you still have the desired kernel installed. Otherwise, install it again. You must then boot that kernel: choose it in the "Advanced options" of the GRUB menu... but a user and a password will be asked: the user is "grub" and the password is at the very end of the output of 'sudo cat /etc/grub.d/01_PASSWORD', to be executed in a terminal. But you had better get rid of that useless password (GRUB's developers say so!): https://trisquel.info/forum/updating-error#comment-117506 Then, remove the newer kernels, e.g., using the "Synaptic Package Manager" in the "System Settings". The configuration of GRUB (which is used!) will be automatically updated: the most recent kernel boots by default.
