Kernel boot problems or is my hard drive failing ?

[Linuxguy123]

If I power down my laptop via the usual KStart->Shutdown means, it can
take up to 4 restart attempts before it fully boots. 

It has no problem launching grub and the kernel selection screen.  That
it does reliably every time.   After that, there are issues.  

Twice I will get a back screen with a flashing cursor.  Then I will get
an ehci -19 error.  Then it will boot properly. 

My fscks are fine.  I had a block error once, about two weeks ago, but
that was with an older F12 kernel after completely crashing during a
resume from suspend to RAM.  

Is anyone else experiencing a problem booting ?   Does this sound like a
kernel problem or is my hard drive failing ? 

Thanks
