[8.0 Beta 1] Can't use my PATA disk (failure - read_dma48) on Asus K8N4-E

Hi,

I meet a second problem when trying to upgrade my system from 7.0-RC3
to 8.0 Beta 1.

The new 8.0 Beta1 kernel can't access to my PATA hard drive (which
works great under FreeBSD 7.0-RC3).

I've got lot's of theses error messages:

ad0: FAILURE - READ_DMA48 timed out LBA=586072364
ad0: TIMEOUT - READ_DMA retrying (1 retries left) LBA=
ata0: reiniting channel...

Need I hand copy all the verbose messages for giving you more information ?

Thanks,

Olivier
