Hi! Mark, I did put in "rootfs=ext3", but, the result is still the same.

Perhaps the kernel is not able to automatically determine the filesystem. When you 'mount' you explicitly tell the kernel what kind of file system is on the device.

Gurus, Need some help in understanding root fs mounting. The setup we have here is our hardware has Xilinx Virtex II pro chip that has System ACE hardware connected to a compact flash. The Virtex II Pro is connected to Local PCI bus which is run by PPC 440GX processor. I have ported the driver for xsysace from ml300 config to our hardware (From OPB to PCI). When I boot over nfs, I can easily mount the partictions on the compact flash. The nodes in /dev directory are: brw-r--r-- 1 root root 254, 0 Jun 3 13:04 xsysacea brw-r--r-- 1 root root 254, 1 Jun 3 13:04 xsysacea1 brw-r--r-- 1 root root 254, 2 Jun 3 13:04 xsysacea2 When I try to boot from the commpact flash, the kernel panics. The edited boot listing is as follows: => bootm ... ... Kernel command line: root=/dev/xsysacea2 rw console=ttyS0,9600 mem=128M ... ... Partition check: xsysacea: xsysacea1 xsysacea2 System ACE at 0xFFFC1000 mapped to 0xD2070000, irq=26, 500472KB ... ... VFS: Cannot open root device "xsysacea2" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 00:00 <0>Rebooting in 180 seconds.. ------- What am I missing here? Any help is appreciated.
