Description Flags
dmesg of blinking ttys none

Description Clyde E. Kunkel 2011-11-07 22:03:06 UTC 
Description of problem:
During boot the tty blinks off every ~6 seconds for ~1 second. After boot, ttys 2-6 blink at the same rate.

Version-Release number of selected component (if applicable):
kernel-3.2.0-0.rc0.git6.0.fc17.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. boot sysytem without rhgb and quiet
2.
3.
  
Actual results:
As above

Expected results:
No blinking ttys

Additional info:
This began with first rawhide 3.2 kernel (kernel-3.2.0-0.rc0.git2.0.fc17.x86_64).  Last kernel that did not blink was kernel-3.1.0-0.rc10.git0.1.fc17.x86_64

VGA=RV630

I am suggesting a severity of medium since the blinking is really annoying and distracting if you are trying to work in one of the ttys, especially with vi or nano.
Comment 1 Clyde E. Kunkel 2011-11-08 15:01:01 UTC 
blinking still present in kernel-3.2.0-0.rc0.git7.2.fc17.x86_64
Comment 2 Dave Jones 2011-11-08 17:26:19 UTC 
is there anything in dmesg when it does this ?

dmesg of blinking ttys

I don't see anything, but then I have no idea what to look for.  Attached is dmesg of a blinking session. 

I do see this in /var/log/messages that I haven't seen with non-blinking kernels.  Why is ColorManager being loaded immediately on bootup?

ok, the backtrace in that dmesg is unrelated, and there's already a bug open on that one.

I don't really have any ideas what could be going on here. My suspicion is that the radeon driver is doing the resyncing, so I'm going to reassign there, perhaps someone else can give you some further debugging ideas.
Comment 5 Clyde E. Kunkel 2011-11-09 18:58:52 UTC 
No blinking with rawhide kernel 3.2.0-0.rc1.git0.2.fc17.x86_64 from rawhide of 20111109.

Will keep open for awhile to see if there is any additional information on what might have been causing this.

Still wondering why color manager is being loaded immediately on boot during dracut time, tho.

Thanks for the assistance.  Strange one.
Comment 6 Clyde E. Kunkel 2011-11-15 18:17:00 UTC 
closing since no reoccurences with a couple new kernels.

Would be nice to know what was causing the blinking.
