 I have recompiled the kernel disabling ultra dma 4:
   wd* at atabus? drive ? flags 0x0aac
 and everything worked, so it seems that the problem lays there.
 Actually, on the config file it says:
 "Disable UDMA 4 which causes data corruption on the Acer Labs chipset on Sun Blade 100 and Netra X1 machines"
