Hi!
I'm not burning DVDs frequently, so I haven't seen this problem before.
I have burned a DVD with growisofs and after that I am seeing a 3-5 min
hang at boot time. No error messages at all, just hang :)
Here is what I have:

The most interesting thing is that I had no such problem before using
my DVD burner!
Is there a way to fix it?

Real programmers don't comment their code. if it is hard
to write, it should be hard to understand.

I tried it, but this one doesn't work for me. Any ideas? -- Sergey Lungu In any series of calculations, errors tend to occur at the opposite end to the end at which you begin checking for errors.

Boot hang (floppy related) (was: Re: atapicam problem (again): hang on boot with DVD burner)

There's a difference between pulling the cable out and disabling the floppy controller through hints which may be significant. If possible, could you try doing the other one of those two to see what happens?> How have you guessed that?Just a hunch... :)> Is there a way to keep it, 'cause I'm using it some times?Try setting debug.fdc.debugflags=255 from the loader, then posting the bits of the dmesg relating to the floppy drive.
