Subject: Re: [KERNEL 2.6.26-rc4]  bugreport : pata_pcmcia with Sandisk
 Extreme III 8GB

Hi,

Strangely, after removing the spin_lock_irqsave
and spin_unlock_irqrestore from the ata_eh_reset,
the pata_pcmcia works properly.

It seedms link->ap->lock is not intialized
by spin_lock_init().

-     spin_lock_irqsave(link->ap->lock, flags);
      link->eh_info.serror = 0;
-     spin_unlock_irqrestore(link->ap->lock, flags);
 


Best Regards
Komuro
