Package: linux-2.6 Version: 2.6.38-3 Severity: important I installed linux-image-2.6.38-2-s390x version 2.6.38-3 on my up-to-date Wheezy system today. It runs in a virtual machine under z/VM 5.4.0 running in an LPAR on an IBM z/890. It IPLed just fine. After the IPL, the system fell idle for a while. Then a CRON job kicked off, which caused a page fault, which caused a kernel oops. Here is the log:

The 2.6.38 kernel is obviously unusable for me. -- .''`. Stephen Powell : :' : `. `'` `- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
