I am Using Nextchip SOC NVP3114 with Sil3114 as PCI to SATA Bridge.

Also using linux kernel version 2.6.14.

Many time The Kernel is detecting the HDD connected on one port of Sil3114.

But when i give mount /dev/sda1 /mnt/sda1 command. Kernel is getting crashed. It hangs and some times prints trace back the then go for toes.


Is there any one who can help in debuggubg this issue or provide pointer which will help me in fiding out whether it is Hardware issue or KErnel Issue?

download and boot a cd based linux live version like knoppix and see what that does.

Many time The Kernel is detecting the HDD connected on one port of Sil3114.
Based on the information you provide above, it look like kernel doesn't support the sil3114 completely.
