http://bugzilla.opensuse.org/show_bug.cgi?id=1041129 Bug ID: 1041129 Summary: Complete freeze with "ata2: COMRESET failed" when on battery power Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: jc@phocean.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 726715 --> http://bugzilla.opensuse.org/attachment.cgi?id=726715&action=edit screenshot of VTY during the crash A few seconds after I unplug the power cord, my laptop starts lagging and freezing more and more until it becomes totally unresponsive. The first symptoms are : applications cannot be launched or closed anymore, gnome-shell starts loosing GUI items, etc. Then the gnome-shell session crashes and in return VTY also become unreachable. On the VTY, the following messages appear : - ata2: COMRESET failed (errno=16) - systemd-journald complaining it cannot write logs. < A photo of the error messages is enclosed here > Same pattern if I try to boot straight on battery power. It fails either early in the boot process or at the login screen. Looking around for the "COMRESET failed" message, I did the following : - update the SSD firmware update to the latest version ; - update the UEFI (Thinkpad T460) Also, note that I freshly install Tumbleweed on Friday. Before, I was on Fedora and never had this issue. So, except a weird coincidence, it is unlikely to be hardware related. Moreover, if my SSD was dying, why it would have no error in SMART and it would fail only on battery power. -- You are receiving this mail because: You are on the CC list for the bug.
