    Default Linux 2.6.27-rc3 Kernel Released

    Phoronix: Linux 2.6.27-rc3 Kernel Released

    It's just shy of one week since Linus Torvalds had released the Linux 2.6.27-rc2, but last night the third release candidate was pushed out. Linus only notes to major changes with the Linux 2.6.27-rc3 kernel and that is the architecture include files continue to be migrated to their new naming/folder convention and the integration of the new Atheros wireless driver. Late last month Atheros had released the ath9k 802.11n WiFi driver for their AR5418+AR5133, AR5416+AR5133, AR5416+AR2133, AR9160, AR9280, and AR9281 chipsets...

    Did somebody try that kernel? There are several issues with it:

    a) If you enable PARAVIRT then this is problematic:

    arch/x86/kernel/paravirt.c:EXPORT_SYMBOL_GPL(pv_lock_ops);

    That makes it impossible to compile fglrx or nvidia drivers (even if you apply the correct ABI changes) until you use a tricky workaround.

    b) Some users reported problems with those drivers:

    * e1000e - Intel(R) PRO/1000 Network Driver (PCI-E)
    * zd1211rw - USB driver for devices with the ZD1211 chip

    So when it comes to wireless, it's safe to buy intel and atheros, but avoid broadcom like the plague, right? What other major manufacturers should a body keep in mind, and what angles are their heads on at?

    (assuming one relies completely on wifi for their laptop internet connection, and doesn't want to have to screw with stuff that doesn't Just Work)

    Well BCM works when you install the firmware, in Debian using

    apt-get install b43-fwcutter

    At least most of the chips work with it then.

    Right, but it's kinda hard to apt-get install something when you have multiple laptops, a wireless router in a different room, no extra ethernet cables, and a wifi chip that doesn't work.

    It's not like a 3d accel driver, where the machine is technically usable without it. Wifi that doesn't Just Work can be a nightmare.

    Then just package what it is loaded. As simple hack:

    tar zcvf b43-firmware.tgz /lib/firmware/b43*
    alien b43-firmware.tgz

    Then you have got a deb - very hard, isnt it?

    *sigh*
    And don't think these machines are just for me, say I get one for my mom or my grandma..

    Nevermind, a general purchasing question has been misinterpreted as a request for workarounds involving the terminal..

    Do you think Intel drivers work without firmware?

    I don't care if a card needs firmware, as long as it comes /on/ the ubuntu install media and I don't have to mess with it.

    I have known all intel hardware to Just Work, from the GPU to the wifi. That's what I want.

    From what I have heard, the atheros drivers (other than madwifi) aren't completely ready, and mileage varies

    Intel should be the safest
