[Bug 763024] Re: plymouth crash - kernel 2.6.39 and psb-gfx graphic driver

[Steve Langasek]

The log in this bug report clearly shows a bug in the out-of-archive
psb-gfx kernel driver, not a bug in plymouth.   You may want to report
this to the psb-gfx maintainers.

Closing this bug report, since there's no way to reassign it.
