System freezes with kernel BUG fs/buffer.c:3359

pvenkman · 2016-01-19 20:17:26

Hello,

I am running a fresh system with Skylake architecture. About once a day the system freezes spontaneously and does not wake up again. Magic keys don't work (but they do if I test them on a not-freezed system), even the reset button fails, only switching the system off and on again will "fix" it. I switched to a dedicated graphics card I had lying around due to this post on the kernel.org bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=109081

[EDIT]
Since I added intel_idle.max_cstate=0 as kernel boot option, the crashes occur less often (now 1-2/day).

I always get a kernel bug message in journalctl when this happens.

Another "interesting" fact - Firefox crashes from time to time (much more often than once a day) - which I am also not used to. BUT I also have these freezes when firefox is not running.

Please support.

Where did you get this idea from? If it was some "solved" topic about Intel CPUs on this forum, skip to the end of this topic and read there

Are you refering to the link I posted? If you look at the end you'll see that the problem is not solved and "they" have still not progressed further than the cstate setting.

https://bugzilla.kernel.org/show_bug.cgi?id=109081#c66

Only use the cstate flag. For me the OSI flag doesn't do anything and the backlight flag breaks brightness. When using only the cstate flag everything appears to work; including brightness.

Oh, I see it now. I thought that maybe you got this idea from one of "Broadwell/Skylake crashes" topics here on Arch forum. Because there were a few and they always end up the same way: install BIOS and microcode updates because the latest CPUs from Intel tend to be unusually buggy

Now, you might be the first to suffer from actual bug in Arch, but we'll see once the updates are in place.
