+Subject: [PATCH] ras-events: quit loop in read_ras_event when kbuf data is
+ broken
+
+when kbuf data is broken, kbuffer_next_event() may move kbuf->index back to
+the current kbuf->index position, causing dead loop.
+
+In this situation, rasdaemon will repeatedly parse an invalid event, and
+print warning like "ug! negative record size -8!", pushing cpu utilization
+rate to 100%.
+
+when kbuf data is broken, discard current page and continue reading next page
+kbuf.
