Hello everyone!

Thanks for that hint!

=2DO1 boots with output (the default is -O2 and does not work, and -Os or=
=20
CONFIG_CC_OPTIMIZE_FOR_SIZE does not work either).

I get an oops, though:
[ 56.305585] Unable to handle kernel NULL pointer dereference (addres=
s=20
000000000000003c)
[ 56.305842] modprobe[896]: Oops 8821862825984 [1]

Logs attached. The same config worked with gcc-4.5.4.

I assume it is best to first make -O1 work and then progress to -O2 lat=
er?

Hello everyone!

Thanks for that hint!

-O1 boots with output (the default is -O2 and does not work, and -Os or
CONFIG_CC_OPTIMIZE_FOR_SIZE does not work either).

I get an oops, though:
[ 56.305585] Unable to handle kernel NULL pointer dereference (address
000000000000003c)
[ 56.305842] modprobe[896]: Oops 8821862825984 [1]

Logs attached. The same config worked with gcc-4.5.4.

I assume it is best to first make -O1 work and then progress to -O2 later?
