Description Cesar Eduardo Barros 2014-02-05 21:36:28 UTC

Description of problem:

If you attempt to set an acpi_osi option with spaces on the kernel command line, grub2 converts the space character into a "\x20".

Version-Release number of selected component (if applicable):

grub2-2.00-23.fc19.x86_64
kernel-3.12.9-201.fc19.x86_64

How reproducible:

Always.

Steps to Reproduce:
1. Add acpi_osi=\"!Windows 2009\" to GRUB_CMDLINE_LINUX at /etc/default/grub
2. Regenerate grub.cfg
3. Reboot

Actual results:

As can be seen at /proc/cmdline, it has been converted to "acpi_osi=!Windows\x202009". The kernel messages do not show it ignoring _OSI(Windows 2009).

The grub.cfg file shows acpi_osi="!Windows 2009" as expected.

Expected results:

/proc/cmdline should have a space character between "Windows" and "2009". The kernel messages should show it ignoring _OSI(Windows 2009).

Additional info:

This issue is the same as bug 923374, which was for Fedora 18.
