-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since nearly 6 month now i have trouble with my unstable ryzen systems. randmom crashes after a couple of hours (<8), (nearly) no load, most times only hard reset is possible to start system new. most times nothing special in system-log (as i know, maybe somebody who know more could see suspected things.) after searching the net: because i am not really familiar with kernel-boot parameter settings, and i have read its necessary to build own kernel (on lists of other distributions) i like to ask: how to fix (work around) or if maybe included in the tumbleweed-kernel the "low load freeze of ryzen" here: ryzen (1700) 8 core processor systems with tumbleweed. i read several links found by google: https://bugzilla.kernel.org/show_bug.cgi?id=196683 https://bugs.launchpad.net/linux/+bug/1690085/comments/69 https://forums.fedoraforum.org/showthread.php?315887-Random-Crashing they suggest to include rcu_nocbs=0-15 is /etc/defaults/grub file correct? GRUB_CMDLINE_LINUX_DEFAULT="video=1920x1200 splash=silent quiet showopts" change to: GRUB_CMDLINE_LINUX_DEFAULT="video=1920x1200 splash=silent quiet showopts rcu_nocbs=0-15 " ?? and run: grub2-mkconfig? is this correct will this work? or is there a better/other solution for tumbleweed? (at the moment here not the newest version of tumbleweed): how to check the tumbleweed version? uname -a Linux becherer1 4.14.2-1-default #1 SMP PREEMPT Fri Nov 24 08:20:07 UTC 2017 (b0610fc) x86_64 x86_64 x86_64 GNU/Linux ============ by the way, as suggested by this mailing-list i have replaced the amd ryzen prozessors because of the segfault problem (i found this problem for my systemsy after the hint on this list). tumbleweed is now running fine with HIGH load (kill-ryzen.sh) script (more than 48 hours) and for others who read inside internet "amd ryzen production date "after week 25 (sometimes is written week30) is fine" THIS is NOT TRUE. at least this type: ryzen 1700 UA 1733PGS has this bug, (2017 week 33) (i have had after a first replacement 4 of this processors all have had this bug) see also here: https://forum.level1techs.com/t/ryzen-pre-week-25-fabrication-rma-issue/1186... ============================== would be happy to get an info how to fix the low load problem to get stable tumbleweed-ryzen-system's. thanks in advance, simoN -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIbBAEBAgAGBQJacJjHAAoJEOuDxDCJWQG+9Y8P+K6tnQsCVoKSI4rrrSWqHGJf aZEcAqmgP1R+DvR6/79iDEx3P5Gq0CWSdGWTY8y385PA5AeurT+C/0n2yE84ojjM SzrzK3b5I+qMPCaHJNrrHpPa6WZW9DCSf1sE88XXDDKBscIVvCsbP2g//IYNMT1F 6ncZRzOmGXGPaeuTvAeQ6tfNKUL1rBA7QKjHwILpUE5hkFY8WW++fhiej9sklXxM QJzpfV0KWJEUtu8aEkV/TShL6N/kjJhwDDPiLO5vV/LkeGIDSLJwqOBkMn0+TYBk CJb72SCQEAvM+dL8Zjnz9Z5IwOKxIZvq0rKxay9UnwtH/KUDMnsznHo9yxcjbp6S czSnr5Aov8BKxnOI6nKFr94oZSk/x0djZZLtsp00LgHnKLkZZTzjQTurQkWy5e6W 4ZUNtSwgpXINqPz87eIgcEvvRNV16HhdstmBf12OSPls9Z1RDDrQR6plEPWU823Q pZUEyEBDNSqArNLNUpW7VPBh0u3BdqWdyQCbuyb2StkVKXi9xtaVZJrzEKYQMELt JLXL5Efz6SlYsSYWsrPWGrwBXWnJ4TSUHmnJTWJQ9W8krap4E9c9X0hBG4uwUL6r 0IJXwNBodJCwS7mAZ+Ri13i7fv5RrIkODklTbyx402GFjFDgIeLF8cKu+5CEYasL RMdkHKjfhQbSTTMGt/c= =aB7T -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
