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=20
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=20
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=3Dy
CONFIG_SYSFS_DEPRECATED_V2=3Dy
CONFIG_WIRELESS_EXT_SYSFS=3Dy
CONFIG_ISCSI_BOOT_SYSFS=3Dm
# CONFIG_GPIO_SYSFS is not set
CONFIG_VIDEO_PVRUSB2_SYSFS=3Dy
CONFIG_RTC_INTF_SYSFS=3Dy
# CONFIG_DMI_SYSFS is not set
CONFIG_SYSFS=3Dy

The system however does not boot. I have also tried passing
"sysfs.deprecated=3D1" 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)=20
which I won't attach to the list:
	https://bugzilla.kernel.org/show_bug.cgi?id=3D48991

Can anyone much wiser than me assist here? How can I help debug this=20
further?
