I have a Via KT333 VT8367 NB, VT8233A SB Board with a Athlon 1800+ proc.  The drive in question is a Ultra DMA 1000 atapi device.  Works under windows 2000 and NetBSD.

restart in default mode, safe mode works but writing to disk is very slow.

 Hi,
  
     It seems that I have almost the same probelms.
 On my home machine that I plan to use as a home
 file-server I can't set up FreeBSD 5.2 and 5.2.1
 In both cases installation hangs with trap 11, during file
 system cunstructure. Nothing happens, cause I still can
 run linux from that disk, where I expected to have FreeBSD.
 
     During fdisk I get message about wrong geomentry, as usual.
 After I run commit, I get:
 
 FAILURE READ_DMA status=51<READY,DSC,ERROR>
 error=10<NID_NOT_FOUND> LBA=245529601
 
 The reason cause my disk does not have LBA 245529601
 It is only 80GB size.
 
 Best regards,
                                 Roman Kurakin

State-Changed-Why:  
ICRC errors are almost certainly because of cable/connector problems. 
Make sure you have spec'd 80conductor cables and have turned them 
the right way around (blue connector in controller ned, grey/black  
for the slave/master device.

 I also get the similiar problem:
  
 Feb  9 15:17:53 dreamland kernel: ad6: FAILURE - READ_DMA
 status=61<READY,DMA_READY,ERROR> error=4<ABORTED> LBA=125440
 Feb  9 15:17:53 dreamland kernel:
 g_vfs_done():stripe/data[READ(offset=192806912, length=16384)]error = 5
 
 It's a probem with HDD or partitions geometry?
