Hi Sebastiaan,

I recently applied the new patch and after building my uClinux (2.6) and
uploading it to my board I stubled onto a problem.
Linux seems to be unable to mount my root romfs included in my image.
This is the log of my starting linux before applying the patch:
Linux version 2.6.19-uc1 ([EMAIL PROTECTED]) (gcc version 4.1.1) #21
Fri Aug
3 12:54:30 CEST 2007
uClinux/COLDFIRE(m520x)
COLDFIRE port done by Greg Ungerer, [EMAIL PROTECTED]
...
uclinux[mtd]: RAM probe address=0x40145d70 size=0x128000
Creating 1 MTD partitions on "RAM":
0x00000000-0x00128000 : "ROMfs"
uclinux[mtd]: set ROMfs to be root filesystem
...
VFS: Mounted root (romfs filesystem) readonly.
Freeing unused kernel memory: 52k freed (0x4012a000 - 0x40136000)
And this is the one after appling the newest patch:
Linux version 2.6.22-uc1 ([EMAIL PROTECTED]) (gcc version 4.1.1) #24 Wed

uclinux[mtd]: RAM probe address=0x40180258 size=0xbd000
Creating 1 MTD partitions on "RAM":
0x00000000-0x000bd000 : "ROMfs"
uclinux[mtd]: set ROMfs to be root filesystem
...
VFS: Cannot open root device "<NULL>" or unknown-block(31,0)
Please append a correct "root=" boot option; here are the available
partitions:
1f00 756 mtdblock0 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(31,0)
In both these cases do you have the filesystem type of your
attached root filesystem enabled in your kernel?
Also are you using any command line to the kernel?
(Should be somewhere early in the boot up trace).
Regards
Greg
