Description

Working kernels (from buildhost) are:
uImage-2.6.21.3-moko10-r3_0_0_2179_0-fic-gta01.bin
uImage-2.6.21.3-moko10-r3_0_0_2288_0-fic-gta01.bin

while

uImage-2.6.21.3-moko10-r3_0_0_2308_0-fic-gta01.bin
uImage-2.6.21.5-moko10-r1_0_0_2350_0-fic-gta01.bin

are not working (gsmd always times out/exits with modem dead message).
rootfs used during testing was
openmoko-devel-image-fic-gta01-20070701120015.rootfs.jffs2

gsmd.log from non-working kernels are always:

Change History

comment:1 Changed 12 years ago by alphaone@…

I narrowed the search down to the changeset in rev2301.
Compiled linux-2.6.21.5 patched with svn rev. 2300 communicates with the modem
while rev. 2301 doesn't.
I don't see anything obvious in that changeset, though...
