  "message": "[S390] stacktrace bug.\n\nThe latest kernel 2.6.19-rc1 triggers a bug in the s390 specific stack\ntrace code when compiled with gcc 3.4.\nThis patch fixes the latest lock dependency validator code (2.6.19-rc1)\non s390 gcc 3.4. The variable sp was fixed to r15 (which is the stack\npointer in the s390 abi) and assigned new values to r15. Therefore,\ngcc 3.4 assigns a new value to r15 and does not restore it on exit (r15\nis supposed to be call save) - the kernel stack is broken. Avoid trouble\nby not assigning any new value to sp (r15).\n\nSigned-off-by: Christian Borntraeger \u003ccborntra@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n",
