Everything works fine on plain 2.6.14.
Since 2.6.14-mm1 I am getting the attached Oops
(grabbed via netconsole, from 2.6.15-rc1-mm2).
After that Oops, the PC is completely dead.
The Oops happens when the saa7134 module is being
modprobed. Any ideas?
(sorry for the duplicate report, in the previous one
I confused the kernel versions)
