After our quick chat on IRC, I remembered that there were additional two
fixes for dl-server posted, but still not on tip.

https://lore.kernel.org/lkml/20250615131129.954975-1-kuyo.chang@mediatek.com/
https://lore.kernel.org/lkml/20250627035420.37712-1-yangyicong@huawei.com/

So I went ahead and pushed them to

git@...hub.com:jlelli/linux.git upstream/fix-dlserver

Could you please check if any (or both together) of the two topmost
changes do any good to the issue you are seeing?

Thanks!
Juri
