--- Comment #25 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- Looks better, but now we get this quite often: -- ==23722==ERROR: Your kernel seems to be vulnerable to CVE-2016-2143. Using ASa\ n, MSan, TSan, DFSan or LSan with such kernel can and will crash your machine, or worse. -- I'll try to figure out what kernel version we need.
