    Subject2.6.28-git8: tg3 doesn't work due to firmware not loading (-git7 is ok)
    From dmesg:

    [asuardi@sandman src]$ dmesg | grep tg3
    tg3.c:v3.97 (December 10, 2008)
    tg3 0000:02:00.0: PCI INT A -> Link[LNKA] -> GSI 11 (level, low) -> IRQ 11
    tg3 0000:02:00.0: setting latency timer to 64
    tg3 0000:02:00.0: wake-up capability disabled by ACPI
    tg3 0000:02:00.0: PME# disabled
    tg3 0000:02:00.0: firmware: requesting tigon/tg3_tso.bin
    tg3: Failed to load firmware "tigon/tg3_tso.bin"
    tg3 0000:02:00.0: PCI INT A disabled
    tg3: probe of 0000:02:00.0 failed with error -2


    But /lib/firmware/tigon/tg3_tso.bin is actually present:

    [asuardi@sandman src]$ ls -l /lib/firmware/tigon/tg3_tso.bin
    -rw-r--r-- 1 root root 7004 2009-01-06 22:58 /lib/firmware/tigon/tg3_tso.bin



    Diffing the .configs one can see CONFIG_KMOD disappeared; and
    the output of the kernel build in -git8 also has the IHEX parts about
    tg3 firmware which are new (I don't recall seeing those in the last
    1000 builds or so ;)

    So which is it, whatever the IHEX part did or the disappearance of
    CONFIG_KMOD (which is in the -git8 patch, indeed) to cause
    this issue ?

    Note that I don't have CONFIG_FIRMWARE_IN_KERNEL, but on
    the other hand I didn't earlier, either... and yes, CONFIG_MODULES=y.


    thanks in advance, ciao,
