Thanks Christopher for your advice. Yes the firmware of the Samsung EVO 840 was updated to the latest one (last firmware Dec.' 13) with the Samsung Magician software. I checked the update twice after a reboot.
I have to add: the new replacement drive is an exact 1:1 copy of the SSD, and shows no problems at all. So I really think - and with above links - this is a hardware related problem between the Samsung EVO 840 and the hardware of the Thinkpad W510's Intel Corporation 5 Series/3400 Series Chipset 6 port SATA AHCI Controller [8086:3b2f] (rev 06) or other components. Side effect is, that network components are also not working as they should, after the hard reset issued by the kernel.. Due to the fact, that this is (and will be) a much common drive for a lot of people, I think this is an important bug. I will investigate further ... -- 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/1266305 Title: [Lenovo ThinkPad W510] Sudden Read-Only Filesystems Status in “linux” package in Ubuntu: Incomplete Bug description: After a while of running the system, the SSD goes into a readonly file system mode.
