    CONFIG_LATENCYTOP=y

    If it is possible. I want to use latencytop to test a TS bug theory.

    # ./latencytop
    Could not open /proc/sys/kernel/latencytop: No such file or directory
    Could not open /proc/sys/kernel/latencytop: No such file or directory
    It will fix that ^^^^

    I got my latencytop binary from: http://o2droid.phj.hu/trac/browser/img/beta/system/xbin/latencytop?rev=51

    Sorry about asking for something else to be added to your kernel but making it compatible with CM7 would help. It would need BOOTCLASSPATH changed, the netd fix for CM7, and a rmt_storage fix in the initramfs. Penguinrepair already has these fixes in his kernel but adding them to your kernel would help debug the rotation bug we have in CM7.
    You can rip out the initramfs from penguinrepair's kernel and look at the changes. :fight:
    Edit: BTW...the kernel is not the source of the touchscreen bug. CM7 for the TU does not have the touchscreen bug using a stock kernel and a modified initramfs. Something in the GB stock install is causing the TS bug...my guess is that CIQ is causing latency in the TS data stream.

    Did you try the wifi fix? Judging by the description for the wifi fix I believe it will work for this new kernel too... see op

    Thank you Bob for your new kernel. It is compatible with CM7 now.

    • Fixes rotation bug
    • OC works(tested with No-Frills)
    • Governers and I/O Schedulers also selectable using No-Frills
    • Apply on boot works
    • Su works fine
    • Touchscreen bug gone

    Looks like the touchscreen bug in stock Gingerbread is gone too.

    Edit: Bug report for WiFi with modules flashed. WiFi error:
    WiFI_BobZ_2.1 - Pastebin.com

    Confirmed from console:
    # insmod /lib/modules/dhd.ko
    insmod: init_module '/lib/modules/dhd.ko' failed (Exec format error)

    Dmesg:
    [ 832.928042] dhd: version magic '2.6.35.7-g4873f0f-dirty preempt mod_unload ARMv7 ' should be '2.6.35.7-g4763763-dirty preempt mod_unload ARMv7 '

    Hope this helps.

    Just wanted to confirm the wifi fix does NOT work with the new kernel. I think that's what Bads3ctor was saying, but I don't fully understand "dev-lish" :confused: so I thought I would post in layman's terms. :D

    Try using SmartassV2 I find that there's no lag when waking and it manages the processors clock more intelligently than interactive when the screen is off.
