Kernel 6.6.3 is missing exFat module

Hello,

Linux 5.4 switched to kernel exFat module, and AUR deleted the exFat dkms module. Kernel 6.6.1 still had a exFat module built in, but kernel 6.6.3 is lacking it completely.

no built in or dkms module means I can only access exFat SD cards with the loop module - too bad.

The module is where it has always been.

What do you mean by accessing SD cards with the loop module?

Re: Kernel 6.6.3 is missing exFat module

linux 6.6.3.arch1-1 in core contains usr/lib/modules/6.6.3-arch1-1/kernel/fs/exfat/exfat.ko.zst
linux 6.6.4.arch1-1 in core-testing contains usr/lib/modules/6.6.4-arch1-1/kernel/fs/exfat/exfat.ko.zst
Is there a mismatch between the version of your running kernel `uname -a` and the linux package's version `pacman -Q linux`?

Re: Kernel 6.6.3 is missing exFat module

In my experience that's usually happened when booting off of a mismatched kernel:initrd. Meaning if you have '/boot/efi' instead of just '/boot' and you upgrade the kernel and do not have the function automated to replace the kernel or initramfs in /boot/efi then you're going to boot of an outdated kernel as far as the loader's/loader-entry is concerned and therefor no modules for you at boot time.
