Problems to keep external luks hdd mounted after boot
My external disks are correctly decrypted and mounted after boot, but a couple of them unmount approximately 2-3 minutes later. The disks are healthy (S.M.A.R.T. tests pass and they work on other operating systems), so the issue seems to occur only after booting on this machine. Every new reboot the problem is in a different drive.
I did the last update in 2025-05-30 and now in 2025-07-05, around 1 month.
I use xfce, xorg and 6.12.36-1-lts kernel, the following setup has worked for years.. until the last update:
cat /etc/mkinitcpio.conf
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(piix ide_disk reiserfs)
MODULES=()
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
FILES=()
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
## This setup specifies all modules in the MODULES setting above.
## No raid, lvm2, or encrypted root is needed.
# HOOKS=(base)
#
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS=(base udev autodetect block filesystems)
#
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS=(base udev block filesystems)
#
## This setup assembles a pata mdadm array with an encrypted root FS.
## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
# HOOKS=(base udev block mdadm encrypt filesystems)
#
## This setup loads an lvm2 volume group on a usb device.
# HOOKS=(base udev block lvm2 filesystems)
#
## NOTE: If you have /usr on a separate partition, you MUST include the
# usr, fsck and shutdown hooks.
HOOKS=(base udev autodetect keyboard keymap modconf block encrypt lvm2 filesystems fsck)
# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"
# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()Errors after boot: sudo journalctl -b -p err

The following log is about:
1) I manually mounted the disk because after reboot it was unmounted
2) I successfully read/write to the disk (using file manager), then after 2-3min the disk unmounts, maybe the problem is about the UAS driver?
