More info: This happened three more times, the last of which I was actually using the computer (as opposed to screensaver engaged and me afk).
I noticed, after reboot, that there was lots of I/O wait (three or even all for CPUs) and extreme lag in starting new xterms or other applications for quite a while, although neither dmesg nor /proc/mdstat showed any reason for it (no resync active, etc). I did not manage to catch which programs were in D state in top, though. I’m trying now with linux-image-4.1.0-1-amd64:amd64 (= 4.1.3-1) which already looks better (not the I/O(?) wait after booting, except once during fsck of a BSD VM, and much shorter then). bye, //mirabilos -- tarent solutions GmbH Rochusstraße 2-4, D-53123 Bonn • http://www.tarent.de/ Tel: +49 228 54881-393 • Fax: +49 228 54881-235 HRB 5168 (AG Bonn) • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg
