I get the same issue on a newly installed Lubuntu 16.04.3 with 'apt upgrade' freshly applied.
/var/log/syslog and /var/log/kern.log grow to 100s of MiB in less than a day. Typical syslog entry is attached (hostname redacted). I am not making hardware changes at the times these entries are made. Note that the kernel reports itself as tainted. This is due to a previous kernel warning issued during the boot-up, which I believe to be unrelated - kern.log extract (hostname redacted) of warning and taint also attached. The laptop reports itself as having the problematic Ricoh devices. relevant hwinfo attached. grepped extract follows Model: "Ricoh R5C832 IEEE 1394 Controller" Vendor: pci 0x1180 "Ricoh Co Ltd" Model: "Ricoh xD-Picture Card Controller" Vendor: pci 0x1180 "Ricoh Co Ltd" Model: "Ricoh R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter" Vendor: pci 0x1180 "Ricoh Co Ltd" Model: "Ricoh R5C592 Memory Stick Bus Host Adapter" Vendor: pci 0x1180 "Ricoh Co Ltd" Workaround is blacklisting devices by adding the following lines at the end of /etc/modprobe.d/blacklist.conf # Stop errors filling up log - see # https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1530187 # Blacklist Ricoh card reader blacklist r592 blacklist r852 This stops messages from appearing in /var/log/kern.log and /var/log/syslog. Cardreader still reads SD cards. graaskaeg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1530187 Title: r852 & r592 IRQ: DMA errors cause log files to grow *HUGE* To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1530187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
