Getting kernel panic on sandybridge as well, freeze on moderate I/O and sometimes get panic messages on shutdown.

The panics are almost certainly BFQv8 related. Reverting to BFQv7r11 makes them go away. I was able to get good panic output by logging to the serial port. I'm not a linux-ck user, rather a standalone BFQ user. I've started a thread on paolo's newsgroup to work through this issue: https://groups.google.com/forum/#!topic/bfq-iosched/80V4U6ak57w Because of these stability issues, I'd recommend linux-ck revert to BFQv7r11.

@graysky I'm definitely getting kernel panics after the system has been up for a few hours. the numlock key doesn't even respond, once the system locks up. Running the standard kernel for now to see if it's still an issue.

@rucci - That is the default for the PKGBUILD except for _BFQ_enable_=y (and NUMA code has been commented for ages now). The only diff you have is enabling BFQ by default but that shouldn't trigger a bug as you activated it through other means before.

I recompiled again with "_1k_HZ_ticks=y", "_BFQ_enable_=y", "_NUMAdisable=y", gcc patch and now it works without kernel panic...

@graysky I haven't had any panics yet. Running the kernel compiled for Haswell, with '_1k_hz_ticks' and bfq enabled.

@graysky Yes, I only installed one disk (/dev/sda) and and enabled BFQ on it. Several hours ago, I checked it with cake-pc# cat /sys/block/sda/queue/scheduler noop deadline cfq [bfq] I am sorry that I did not try recompiling `linux-ck=4.6.5` with `_1k_HZ_ticks=`. I just changed `grub.cfg` and rebooted with the stock kernel ... Everything seems to be working fine ... I am wondering what is going on when the system freezes. So if you require any other information, please let me know.

graysky commented on 2016-07-29 13:19 (UTC)

So two reports of the new bfq causing panics? Can you both verify that you have a drive set to use bfq? I don't see how tick rate plays into the equation.

mssdvd commented on 2016-07-29 09:20 (UTC)

It works if I disable "_1k_HZ_ticks" option

Cake commented on 2016-07-29 08:39 (UTC)

@rucci I have the same problem (Gnome BFQ Ivybridge) after updating to 4.6.5-2. I have to restart by pressing the reset button on my machine when the system freezes...
