You may have noticed that the site had a lot of downtimes recently.

I was having a daily kernel panic and weired file system corruptions, which I first tought were coming from the successive crashes and reboots.

However, while it happened again and again and I could not find any good reason for that, I became more doubtful about my hardware and finally found the culprit.
I booted on Memtest, installed with zypper from the repo, which immediately displayed a lot of errors. The tedious task of isolating the faulty memory module revealed that it was one from a Ballistix bundle that I bought just 3 months ago.

I usually use Kingston or Corsair and never had such a problem, but maybe I was just lucky. I will test now the customer service of Ballistix.
