Sorry for late replying. Manufacturer: Packard Bell. Product: Packard Bell Dot-S. it/10, model number KAV 60.
You maybe puzzled reading that Bios manufacturer is ACER but, that is, the machine is actually an Acer AOD250 rebranded. I upgraded the bios to the versions released by Acer (PB never released upgrades) and they have been working flawlessy since...4-5 years. Furthermore, bios by Acer has exactly the model number of my machine, KAV60. Thanks for your time. -- 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/1514198 Title: Gpu hung on i915. Status in linux package in Ubuntu: Incomplete Bug description: Hello, my gpu, an old GMA945 on i915, randomly crashes. This is an extract of the kernel log reporting the crash. I have to admit, to be precise, that this defect has been occuring just after upgrading to 15.10 and kernel 4.x; before of that, with ubuntu 15.04, it never occurred. Thanks.
