You have a really surprising setup. How is it even possible to have
bumblebeed on PPC32 ? the package is supposed to be empty for this
arch.

What's the output of:

$ apt-cache policy bumblebee
$ dpkg -L bumblebee

Thanks

The changes in `/var/log/syslog` after `modprobe nouveau` (are the same
as in `dmesg`):

Bug#843448: linux-image-4.8.0-1-armmp-lpae: fails to boot on Odroid-Xu4 with rootfs on USB

2016-11-06 Thread Vagrant Cascadian
Package: src:linux
Version: 4.8.5-1
Severity: important

When upgrading to linux 4.8.x on an Odroid-XU4 system, it no longer
detects the USB sata adapter where rootfs is located.

Downgrading to the 4.7.x kernel from jessie-backports works fine.

I didn't see anything obviously missing when diffing /boot/config-*.

Boot log attached.

If there's nothing obvious fromt the boot log, I can try taking it
offline and doing an install with stretch or sid to do more debugging.


live well,

Yes, I agree. Per se it's not a bug. I filed this against cifs-utils
because I was imagining a user-space interface to influence the
kernel.

No, always. I should have used another word. In English, eventually
means that something will happen, whereas in German and possibly
French, it might suggest that something possibly happens, or not.

Seems a bit weird that this is hard-coded.

> Again, have you tried mount -o remount?

Yes, but unfortunately it doesn't have the desired effect. It just
blocks until the 120 seconds are over. It'd be a nice interface
though!

As far as I know, it's not affected, because NFS is datagram-based,
whereas CIFS is session-based. It's a bit like mosh and SSH…

Bug#843349: linux-image-4.7.0-1-amd64: Intermittently high system load, sluggish response, no /proc//stat utime,stime,etc. reported

2016-11-06 Thread Tom Lee
Package: src:linux
Version: 4.7.8-1
Severity: important

Dear Maintainer,

Experienced poor system-wide performance since linux-image-amd64 pulled
down 4.7.0-1. Tried to investigate what was going on, only to discover that
tools like top/htop were unable to report per-process
CPU time (though system-wide CPU stats based on /proc/stat were still
reporting fine). Further analysis shows /proc//stat CPU fields stuck at
zero.

The impact seems to be emphasized when a brief but moderately heavy load
occurs (e.g. kicking off CMake, performing certain operations within
CLion/other IDEs, etc.): in 4.6.0-1 you see a brief uptick in CPU burn in
top/htop that settles quickly; with 4.7.0-1 the effect of the burst of
activity
seems to be emphasized -- load average drastically and quickly increases,
CPU activity goes through the roof and the system becomes intermittently
unresponsive.

The system is ultimately usable, but feels very sluggish overall.

Downgrading to linux-image-4.6.0-1-amd64 fixed all symptoms. Haven't yet
tried 4.8.0-1 from unstable, not sure if it's impacted.

Thank you!
Tom
