Hi,
I'm not really sure where this should be reported, but here it goes.
After installing openSUSE 11.2 on my testbed nx6325 I noticed that resume (from suspend to RAM) stopped working on it. Apparently, it hanged while switching from the console back to X and the box remained completely unresponsive after that (it didn't even react to the magic sysrq). However, it used to work just fine with -rc7 and openSUSE 11.1, so I figured the problem was related to the new X driver, which is radeon module version 6.12.4 (xorg server 1.6.5).
So, I started to investigate and found that after a suspend from a framebuffer console, the resume had always worked. However, when I switched from X to the framebuffer console, suspended, resumed and switched back to X, the box hanged immediately just like during resume after a suspend from under X. [There also were some problems when switching from X to the framebuffer console and back which seemd to be independent of suspend/resume (in short, the screen stays black after a switch from the framebuffer console to X and you need to kill X to fix this).]
Later, however, I discovered that if the box was booted into runlevel 3, then suspended to RAM and resumed, and then switched to runlevel 5, I could log into X and suspend/resume without any problems for many times. OTOH, after booting directly into X, the first attempt to resume always resulted in a black screen and a hard hang.
I wonder what's up in there.
[Hibernation/resume works 100% of the time AFAICS.]
Thanks, Rafael
