Subject: Regression in linux-firmware-20250917 for mt7921e driver
Date: Fri, 19 Sep 2025 19:18:21 +0100	[thread overview]
Message-ID: <87bjn6fgr6.fsf@gentoo.org> (raw)

Hi,

I'm forwarding a downstream report in Gentoo from
https://bugs.gentoo.org/963106 which also came up in Arch at
https://gitlab.archlinux.org/archlinux/packaging/packages/linux-firmware/-/issues/29
and on the linux-firmware gitlab at
https://gitlab.com/kernel-firmware/linux-firmware/-/merge_requests/684.

The user describes it on the Arch bug as:
"""
core/linux-firmware-mediatek@20250917-1 causes network to fail startup
and dramatically slows down basically every operation in the kernel.

symptoms are a pegged kworker thread at 100% cpu util, shutdown being
prevented, extremely slow commands like sudo, filesystem access. I
suspect a interrupt storm of some sort.
"""

And another mentions that removing the module w/ modprobe -r mt7921e hangs.

thanks,
sam
