The log files on my laptop, /var/log/messages and /var/log/warn, will grow HUGE with the following repeated over and over along with some extraneous related log entries: 2014-08-15T12:18:41.396981-04:00 localhost kernel: [17310.691176] r592: IRQ: card added 2014-08-15T12:18:41.396983-04:00 localhost kernel: [17310.691178] r592: IRQ: DMA error . <snip> . 2014-08-15T12:18:41.397001-04:00 localhost kernel: [17311.223846] r592: IRQ: card added 2014-08-15T12:18:41.397004-04:00 localhost kernel: [17311.223847] r592: IRQ: DMA error On any given day, there will be tens of thousands of these entries such that /var/log/messages and /var/log/warn will both exceed 3GB within a day (over 6GB total). I believe that this bug is generated due to the presence of a Ricoh R5C592 Memory Stick Adapter on my laptop and which has never been properly recognized by the stock linux kernels. Apparently, the kernel developers keep trying to make it work but have now introduced a "bigger" problem so to speak since it is now causing all these extraneous error messages to be generated in the logs. I am seeing this bug on OpenSUSE with kernel-desktop versions 3.15.6 and 3.16.0. This bug does not appear to be present in the OpenSUSE stock 3.11.6 and 3.11.10 kernels. I have since reverted back to the earlier kernels that don't have this problem. This bug has also been reported at Red Hat's bugzilla at: https://bugzilla.redhat.com/show_bug.cgi?id=1119361 IMHO, this bug needs to be fixed prior to the release of OpenSUSE 13.2. FYI, Gordon Reproducible: Always Steps to Reproduce: 1. Boot 2. Wait a while. It sometimes takes an hour or two for the log errors to begin at top volume. Actual Results: Logs grow *HUGE* with r592IRQ: DMA errors and related entries. Expected Results: Logger should not produce error messages of this magnitude and size. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
