Re: [PATCH 2/3] Re: sil3114 data corruption

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This will add the sil3114 back to the controllers with the mod15 bug. Without 
this patch no workaround for this controller is done and people might/will 
suffer from data corruption.

Also rather trivial, though with a huge effect, the speed for the effected 
disks will go down from about 45-50MB/s to 20-25MB/s. But better safe than 
lost data or damaged filesystem.
