Bugzilla bug #14543 describes a very similar issue involving ata flushing which is RESOLVED and available in patch "libata: retry failed FLUSH if device didn't fail it" which is applied from kernel 2.6.33-rc1 http://mirror.celinuxforum.org/gitstat//commit-detail.php?commit=6013efd8860bf15c1f86f365332642cfe557152f
The bug report https://bugzilla.kernel.org/show_bug.cgi?id=14543 also has a script that repeatably creates the read-only effect, but I can not get this script to create the effect here - can anyone create a script that reliably replicates this fault? Comment #7 From Andrey Vihrov 2009-11-05 09:43:18 ------- Created an attachment (id=23658) [details] dmesg with ext4 failure Yes. I was able to trigger it by running two scripts in parallel: while true; do echo > test && sync && rm test && sync || break ; done and while true; do for FILE in /sys/class/scsi_host/*/link_power_management_policy; do echo "min_power" > ${FILE} && echo "max_performance" > ${FILE}; done && sleep 1 ; done ** Bug watch added: Linux Kernel Bug Tracker #14543 http://bugzilla.kernel.org/show_bug.cgi?id=14543 -- Repetitive massive filesystem corruption https://bugs.launchpad.net/bugs/528981 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
