It's true that the segfault bug only affects first gen Ryzens, but 2. is not true ; Ryzen+ systems can still suffer from the freeze issue. Only the latest BIOS updates seem to solve it, but maybe not for everyone on Linux, depending on the kernel version used too]]> Thu, 06 Jun 2019 02:21:15 +0000 https://forum.asrock.com/forum_posts.asp?TID=11402&PID=63619&title=taichi-bios-3-20-linux-freeze#63619 https://forum.asrock.com/forum_posts.asp?TID=11402&PID=63610&title=taichi-bios-3-20-linux-freeze#63610 Author: Paolo61

Fixed with the new BIOS 3.4.
Works also with new kernel 5.1.5

Ah. Thanks. I will test the C6 issue on my 2700x, as I have it off for some reason. I might have justnthrown that into the pot while first setting my system up, unaware that it did not apply to my CPU. Is this the same issuenthat is addressed by setting Low Current to Tyoical instead of Idle?]]> Wed, 08 May 2019 10:50:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=11402&PID=62806&title=taichi-bios-3-20-linux-freeze#62806 https://forum.asrock.com/forum_posts.asp?TID=11402&PID=62805&title=taichi-bios-3-20-linux-freeze#62805 Author: shmerl

There are two issues.

1. Segfaults under heavy multi-threaded load. Affects early first generation Ryzen chips.
2. Freezes due to C6 (idle). Affects all first generation Ryzens.

If you are still getting hardware freezes even with Ryzen+, then you got some really bard part. Try RMAing it. A lot of Ryzen+ don't have the freeze issue. I suppose it still happens in some defective chips, but only in some minority, unlike in first generation Ryzens.

I was able to change few of the BIOS parameter bu I can't find the LLC for the RAM, in any case now it freeze only when it start and after few reboot it works OK for the day.]]> Sun, 05 May 2019 16:24:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=11402&PID=62758&title=taichi-bios-3-20-linux-freeze#62758 https://forum.asrock.com/forum_posts.asp?TID=11402&PID=62722&title=taichi-bios-3-20-linux-freeze#62722 Author: Paolo61

hi, when I set up the box I solved the issue of seldom random freezes enablig the ram voltage to manual offset at -0,1v (now I'm @ -0,08) and setting the two ram LLc voltages to 3.

I enabled also the OC voltage profile even if I didn't oc neither the processor nor the ram. Still, I'd enabled the XFR/PBO.

More on cstates and so on, in my notes for this issue, I'd also 'disable cool and quiet'.

[QUOTE=shmerl] The freeze bug affects all first generation Ryzens, no exception. Just not 100% of them. The week doesn't matter.

You are mixing it with another hardware bug, that caused segfaults due to some messed up memory access. That was indeed fixed in later batches. But the freeze issue was not. Only Zen+ fixes it.[/QUOTE

Help me out here. The segfaults which manifested to ferociously in linux on 1st gen Ryzens was due to the pre week-25 hardware flaw?
