I have a NM70I-847 motherboard, and I installed Debian 9 Stretch on it recently. After installation, the system began to reboot randomly without any warning.
I used to run Debian 7 Wheezy on this motherboard, the RC6 sleep feature of the CPU’s graphics need to be disabled to prevent such issue. It should be very easy to fix just need to add parameter “
i915.i915_enable_rc6=0” to grub boot option.
But the method seems not working (or deprecated) — after applied the fix computer still keep rebooting on its own. Message like the following can be observed from dmesg:
i915: unknown parameter 'i915_enable_rc6' ignored
Yep, that’s why this fix is not working, because this parameter has been ignored by system. Continue reading (Updated method) Prevent Debian Linux randomly reboot on Biostar NM70I-847
Server: Ubuntu 14.04
It’s very slow when SSH into the server.
After type the password and press enter, I have to wait about 5 secs before I can see the command prompt. Finally I found there was a process
python3 /usr/lib/update-notifier/apt-check --human-readable
holding the login procedure.
This script is used to display package updates info when you login (like “XXX packages can be updated”). And it’s called by “/etc/update-motd.d/90-updates-available” during the login procedure.
So in order to speed up the login procedure, I commented out all lines in
Newly installed Ubuntu 14.04 server and samba on a new PC.
When I was trying to create an array by execute the mdadm command with sudo, I got this error message:
no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory
Somehow, the sudo command was successfully completed, but the error message is annoying. I was thinking this maybe a mdadm bug, but after tried some other commands – I found each time when I was execute a command with sudo I got this error message. Weird! After googling around I found some pages relating to this problem. Looks like this seems to be a issue with samba and libpam-smbpass?
