Downgraded the server to Ubuntu 14.04.5: no issues with the following kernel versions:
* linux-image-3.13.0-96-generic * linux-image-4.2.0-42-generic I am attaching some lines from dmesg where the "fault_state(0x265d)" is present but does not lead to I/O errors or filesystems mounted read only: even under high load the system behaves normally. As stated before I am unable to run apport-collect (or any other command) after that I/O errors have been noticed. ** Attachment added: "Behaviour with kernel 4.2.0 on trusty" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1625718/+attachment/4744521/+files/kernel-4.2.0.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1625718 Title: I/O error after mpt2sas fault_state 0x265d Status in linux package in Ubuntu: Confirmed Bug description: After a write intensive operation (like dd if=/dev/zero of=bigfile) an I/O error is issued and the filesystem is mounted read-only. Further read attempts from the storage result in more I/O errors. The RAID controller is a Dell/LSI SAS2008 FWVersion(06.00.00.00), ChipRevision(0x03), BiosVersion(07.07.00.00) managing just one RAID10 array with four disks. The following kernels have been tried and gave the same problem: * linux-image-4.4.0-36-generic * linux-image-4.7.4-040704-generic * linux-image-4.8.0-040800rc7-generic All disks are clean when inspected with smartctl.
