During boot, using a genkernel created initramfs the following error is displayed: >> Activating mdev ls: : No such file or directory >> Determining root device... >> Mounting root... the error "No such file or directory" occurs in the function "swsusp_resume" in /etc/initrd.scripts when the variable REAL_RESUME is an empty string.

Created attachment 155057 [details, diff] patches function swsusp_resume in /etc/inird.scripts to check for an empty variable before using it
That patch is essentially a no-op. ${REAL_RESUME} is already checked in linuxrc before that function is called. What version of genkernel are you using?
(In reply to comment #2) > That patch is essentially a no-op. ${REAL_RESUME} is already checked in linuxrc > before that function is called. What version of genkernel are you using? > genkernel 3.4.9 kernel-genkernel-x86-2.6.24-gentoo-r8 and initramfs-genkernel-x86-2.6.24-gentoo-r8 built with the "genkernel all" command This is from a fresh install of Gentoo 2008.0-beta2 into a VMWare Workstation 6.0 VM.
I found something else. I took a look at linuxrc and its includes and I only found two places where REAL_RESUME is set. The first is in linuxrc where the script sets up variables based on the passed in kernel parameters. if the "real_resume=xxx" parameter is not passed in as a kernel parameter, the REAL_RESUME variable does not get a value. Later is in a call to startLUKS() (in etc/initrd.scripts included by linuxrc). This is called before swsusp_resume(). Here's the relevant part: if [ -n "${CRYPT_SWAP}" ]; then openLUKS "swap" if [ -z "${REAL_RESUME}" ] then # Resume from swap as default REAL_RESUME="/dev/mapper/swap" fi fi Here REAL_RESUME is initialized to "/dev/mapper/swap" if it is empty, but this check only occurs if CRYPT_SWAP is *not* an empty string. Unfortunately CRYPT_SWAP is empty at this point (at least for me) Finally in swssup_resume() is this line: local device=$(ls -l "${REAL_RESUME}" | sed 's/\ */ /g' | cut -d \ -f The ls returns "ls: : No such file or directory"
I'm pretty sure this was fixed already in one of the 3.4.10_pre versions. Upgrade to the latest and check again. Reopen this bug if it's still an issue.
I keep it closed however 3.4.9 is considered as stable and 3.4.10 as ~. Any plan to apply this patch to the stable version ?
No
Confirmed this bug does not occur in 3.4.10_pre10
