Doc Type: Bug Fix
Doc Text:
Cause: CONFIG_SYSFS_DEPRECATED config was enabled by mistake during the test phase - it was necessary in RHEL5. Consequence: Some userspace tools (such as udev) are confused as they rely on the newer sysfs layout and the option above forced the old style sysfs layout to be used. Fix: disable CONFIG_SYSFS_DEPRECATED in the configuration file for kernel-rt-vanilla. Result: System works fine, without the warnings and errors caused by the presence of CONFIG_SYSFS_DEPRECATED.

Description David Sommerseth 2011-06-02 13:45:08 UTC 
When booting kernel-rt-vanilla-2.6.33.9-rt31.66.el6rt, the following errors are found:

udevd[1140]: udev: missing sysfs features; please update the kernel or disable the kernel's CONFIG_SYSFS_DEPRECATED option; udev may fail to work correctly 
<3>udev: missing sysfs features; please update the kernel or disable the kernel's CONFIG_SYSFS_DEPRECATED option; udev may fail to work correctly

When checking the kernel config, the following options were found:

$ grep SYSFS config-vanilla-x86_64 
CONFIG_SYSFS_DEPRECATED=y
CONFIG_SYSFS_DEPRECATED_V2=y
CONFIG_ACPI_SYSFS_POWER=y
CONFIG_WIRELESS_EXT_SYSFS=y
CONFIG_GPIO_SYSFS=y
CONFIG_RTC_INTF_SYSFS=y
CONFIG_SYSFS=y
