Hello,
I have a problem with runnig L4Linux. On both native and ux, the error
is similar. (see the following log)
Before this problem happened, I didn't any problem.
IMHO, dm_phys seems to be the source of this error.
I tried different mode (uclibc, dietlibc) with the same error.
Best regards,
Jugwan
