Only hard reset was working. Hadn't any logs within the systemd-journal. (Maybe, because I stripped down the debugging in my kernel config).<br />My second test on another computer (i7 laptop) leads to an crash during USB stick test with f3write/f3read.<br /><br />Sorry, that I must report this.<br /><br />Regards sysitosMikehttps://www.blogger.com/profile/12391045215046883684noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-58346593789104387782015-08-06T16:45:44.096+10:002015-08-06T16:45:44.096+10:00Thanks for the quick feedback.

Let's see if it has any impact on the other issues out there as well but sometime in the near future I'll include this patch in the next BFS.ckhttps://www.blogger.com/profile/02904761195451530213noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-19798825056945469472015-08-06T16:00:59.926+10:002015-08-06T16:00:59.926+10:00Oops, forgot to mention, this is with the patch yo...Oops, forgot to mention, this is with the patch you linked included.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-44849758362718104742015-08-06T16:00:03.245+10:002015-08-06T16:00:03.245+10:00I scrubbed 3 times i a row without a lockup, so I ...I scrubbed 3 times i a row without a lockup, so I guess this patch is still needed.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-36786915560588309072015-08-06T09:53:34.282+10:002015-08-06T09:53:34.282+10:00There's a pattern here and it's almost cer...There's a pattern here and it's almost certainly related to the warning I gave in the announce post.

As i said connection are fine, just a browser behavior is weird. And this thing never happens with mainline kernel so i dont think i can reproduce it.

What I suspect is happening is there's a race condition in the driver itself that is brought out by using BFS and is far less likely to happen on the mainline kernel. This means unless you can reproduce it on the mainline kernel and report the bug, I have no way to help you with it unfortunately.ckhttps://www.blogger.com/profile/02904761195451530213noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-81680968652238253472015-08-04T08:52:36.433+10:002015-08-04T08:52:36.433+10:00Hello and sorry for bad english.

It is not about some last releases, because i had this problem more then year ago.<br /><br />After some uptime(more then 6-8 hours) all sites in any browser load only after 10-15 seconds? in the same time there is no problem with connection. coz there is no packets lost when i ping some url or use curl/torrent clients to download something. At first i thought its something with r8169 module for my Realtek RTL8168, so i changed it to r8168-ck - but that didnt help. So maybe it is with bfs and my harware?<br />Pls direct me which additional information do you need to help fix this problem, any logs etc. So i can post them somewhere. Did anyone ever have the same problem as me?Archuserhttp://archlinux.orgnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-75911765468978898182015-08-04T05:29:54.645+10:002015-08-04T05:29:54.645+10:00Thanks for the update.
