Message-ID: <bug-63981-13602@https.bugzilla.kernel.org/> Date: Mon, 28 Oct 2013 19:38:44 +0000 From: bugzilla-daemon@...zilla.kernel.org To: linux-ext4@...r.kernel.org Subject: [Bug 63981] New: Bad: Buffer I/O errors make disk unusable https://bugzilla.kernel.org/show_bug.cgi?id=63981 Bug ID: 63981 Summary: Bad: Buffer I/O errors make disk unusable Product: File System Version: 2.5 Kernel Version: 3.12.0-rc6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: ext4 Assignee: fs_ext4@...nel-bugs.osdl.org Reporter: scalg1@....ch Regression: No Created attachment 112591 --> https://bugzilla.kernel.org/attachment.cgi?id=112591&action=edit dmesg of the errors causing the problem When I use my laptop, suddenly the SSD disk become unusable. The disk is mounted in read-only mode and the only way to get it work again is to reboot. During the reboot, the file system check, fixes the errors and I can use the laptop for some hours after that the problem appear again. This problem is difficult to reproduce because there are no precise steps to perform in order to cause the I/O errors showed by the attached dmesg. I had the same problem using kernel 3.11.5 and 3.10.6. I use a Sony VAIO pro (Sony Corporation SVP1321C5E/VAIO, BIOS R1040V7 09/09/2013). ============================ Information about my system: bash-4.2# cat /proc/scsi/scsi Attached devices: Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: SAMSUNG MZNTD256 Rev: DXT2 Type: Direct-Access ANSI SCSI revision: 05 ======================================== /etc/fstab /dev/sda1 / ext4 defaults 1 1 /dev/sda2 /home/ ext4 defaults 1 2 /dev/sda3 /media/hd1 ext4 defaults 1 2 #/dev/cdrom /mnt/cdrom auto noauto,owner,ro,comment=x-gvfs-show 0 0 /dev/fd0 /mnt/floppy auto noauto,owner 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 proc /proc proc defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 tmpfs /tmp tmpfs defaults,noatime,nodiratime,mode=1777 0 0 tmpfs /var/spool tmpfs defaults,noatime,nodiratime,mode=1777 0 0 tmpfs /var/tmp tmpfs defaults,noatime,nodiratime,mode=1777 0 0 /proc/version Linux version 3.12.0-rc6 (root@...kstar) (gcc version 4.8.1 (GCC) ) #1 SMP Sun Oct 27 19:02:16 CET 2013 Attached you will find the relevant part of dmesg.
