Subject: CONFIG_SYSFS_DEPRECATED & CONFIG_SYSFS_DEPRECATED_V2 appear to not
 work

Hi all,

Firstly, please CC me in replies as I am not subscribed to the list.

I'm trying to build kernel 3.5.4 and 3.6.2 to work with EL5. Each time I 
try to boot this kernel, I get a panic stating it can't find /

The same kernel config works correctly in EL6 (without the 
CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2 options set)

The documentation I have found states that for compatibility with EL5, I 
should enable the CONFIG_SYSFS_DEPRECATED and 
CONFIG_SYSFS_DEPRECATED_V2 options in General Setup.

I have done this as shown:
# grep SYSFS /boot/config-3.5.4-4.el5xen.x86_64
CONFIG_SYSFS_DEPRECATED=y
CONFIG_SYSFS_DEPRECATED_V2=y
CONFIG_WIRELESS_EXT_SYSFS=y
CONFIG_ISCSI_BOOT_SYSFS=m
# CONFIG_GPIO_SYSFS is not set
CONFIG_VIDEO_PVRUSB2_SYSFS=y
CONFIG_RTC_INTF_SYSFS=y
# CONFIG_DMI_SYSFS is not set
CONFIG_SYSFS=y

The system however does not boot. I have also tried passing
"sysfs.deprecated=1" on the kernel line in grub with no success.

I cannot seem to find anything further that could cause this issue other 
than a fault in these kernel options.

I have added a few attachments (kernel config, screenshot of panic) 
which I won't attach to the list:
	https://bugzilla.kernel.org/show_bug.cgi?id=48991

Can anyone much wiser than me assist here? How can I help debug this 
further?
