RE: XPS_LL_TEMAC works correctly?

[Mohammad Sadegh Sadri <mamsadegh@hotmail.com>]

I solved the problem,=20

As i said,=20
problem was : kernel could easily mount the root file system on NFS and beg=
in init , but after that every thing stopped and there was no more progress=
.=20

My problem was with the kernel command line parameters :=20
console=3DttyUL0 console=3Dtty0 root=3D/dev/nfs.......

the second console parameter was the source of the problem, when init is ex=
ecuted, the second parameter caused no more messages to be written on the s=
creen.

I tested using both LL_TEMAC 1.00a and 1.00b , both work well.=20
thanks.
