Re: System becomes unusable when copying a large file via USB into HDD

[Sreyan Chakravarty <sreyan32@xxxxxxxxx>]

I have some good news.

The workaround :

vm.dirty_background_bytes = 3000000
vm.dirty_bytes = 5000000 

worked wonders for me.

I can now copy and watch YouTube at the same time.

Thank you and hoped this is fixed in upstream soon.

I don't think it is I missing the point.  I already informed you of my system's configuration.  So, I found
it odd you'd be asking me for the additional test.  Thus, my query to you.

Well, https://bugzilla.redhat.com/show_bug.cgi?id=1738828

Would appear to verify that.
