Kernel Log: Coming in 3.10 (Part 3)

Filed under

For Linux 3.10, the kernel developers have modified code designed to protect Samsung laptops from faults caused by a problem with garbage collection in the UEFI firmware. The changes mean that the previously sometimes over-eager protection feature, which had occasionally blocked machines from other manufacturers from setting or modifying UEFI variables, will swing into action less frequently. A recent test by c't magazine, for example, found that several test machines were missing UEFI entries for booting the installed Linux OS following UEFI Linux installation, due to UEFI entry creation having been blocked by this feature. Users can solve situations like this by using efibootmgr on a LiveCD Linux, such as Fedora 18 or Ubuntu 12.10, that doesn't contain the code to protect Samsung notebooks and manually create a UEFI boot entry; obviously this option should not be used with a Samsung device. Details of the approach adopted by the revised protection feature can be found in a blog entry by kernel developer Matthew Garrett.


Linux can now slow the timer interrupt for individual CPU cores, which normally fires 100, 250 or 1000 times per second, to just one interrupt per second.

  • Report: Red Hat could be a Google takeover target – a deal wouldn’t be cheap
    Is Red Hat on the shopping list for Google? Could be. But the cost would not be cheap with Red Hat’s stock having nearly doubled in price over the past year. A takeover would likely cost more than $30 billion and spark a bidding war. At that price a deal would rank among the most expensive ever in tech. A top executive for the cloud behemoth tells Bloomberg News that Google is “constantly on the lookout for a major acquisition.” Growing Google’s cloud business is the responsibility of Diane Greene as chief executive of Google Cloud. And Raleigh-based Red Hat (NYSE: RHT) is a cloud player, providing technology services and support for a growing number of clients. In fact, CNBC’s Jim Cramer just days ago cited Red Hat as one of his “cloud kings.”

  • The ability to correct errors in GPLv2 compliance: the right thing to do
    Today, six more technology companies – CA Technologies, Cisco, HPE, Microsoft, SAP and SUSE -- have all committed to offering the GPLv3 cure approach to licensees of their GPLv2, LGPLv2.1 and LGPLv2 licensed code (except in cases of a defensive response to a legal proceeding). The GPLv3 cure approach offers licensees of GPLv2 code a period of time to come into compliance before their licenses are terminated but does not involve the relicensing of the code under GPLv3.
