Hi,

System:  
Abit MAX3 , P4,1GB ram,   
Distri: mandrake 10, Yoper  
4x160GB SATA on Sil3114 as SCSI /dev/sda ..sdd  
1x80GB ATA on /dev/hda  
  
Created RAID5 and RAID0 on 3 HDs,   
md0 *raid0* (sda2,sdb2,sdc3)   
md1 *raid5* (sda3,sdb3,sdc3)  
  
What happens:  
The problem is reproducable:  
Each time I copy more than 1GB in KDE to md0 the PC almost freezes.  
Interesting is that it seems KDE System Guard shows me physical memory  
running full, and after that it shows {stilled} on the copy window.  
The HD leds are on (not blinking!) and its impossible to do anything with  
this mount.  
  
root@t-rex root # hdparm -tT /dev/sda  
  
/dev/sda:  
 Timing buffer-cache reads:   3480 MB in  2.00 seconds = 1739.40 MB/sec  
 Timing buffered disk reads:  164 MB in  3.00 seconds =  54.64 MB/sec  
root@t-rex root #  
  
After reboot I can see this:  
 
root@t-rex root # cat /proc/mdstat  
Personalities : [raid0] [raid5] [multipath]  
md1 : active raid5 sdc3[2] sdb3[1] sda3[0]  
      261730816 blocks level 5, 128k chunk, algorithm 2 [3/3] [UUU]  
      [=========>...........]  resync = 49.5% (64786432/130865408)

md0 : active raid0 sdc2[2] sdb2[1] sda2[0]  
      73256064 blocks 128k chunks  
  
unused devices: <none>  
  
My guess is that the driver sata_sil caches the transactions and doesnt  
writes the data fast enough... and that leads to freezing.  
 
Something maybe related: 
I dont use the ata driver cause it never recognised 2 hds: 
/dev/hde,f,g,h should be there but it took min 10 min to recognise them 
and only e and g were accessible... 
  
My kernel is: 2.6.7 from kernel.org  
  
Ive googled a bit and fount that some ppl out there have similar problems.  
Some explain they got over the problem with some modules compiled/not 
compiled... 
It doesnt work. 
the config file is attached.
