Bug 27987

Summary: New ATA Driver failure with VIA Southbridge VT82686A
Product: Base System Reporter: feh
Component: kernAssignee: Søren Schmidt <sos>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: Unspecified   
Hardware: Any   
OS: Any   

Description feh 2001-06-09 13:50:01 UTC 
I am currently running FreeBSD 3.5.1 on a Gericom NB with AMD K6-2/500
196 MB RAM, VIA integrated chipset (Trident Cyber Blade etc.). Disc is
Toshiba MK6015MAP (6 GB). 
In an attempt to upgrade to 4.1/4.2/4.3 I harvest a complete desaster:

- The installation succeeds with some write failures.
- After the first reboot the file system is "mangeled" and the system 
  starts with a default shell, since even /etc/fstab is not evaluated. 
- Strange enough, some parts of /bin, /sbin, /usr/.. are intact thus some
  command work.
- No chance to fix it manually via fsck - to many failures (like
  (double used inodes etc.).
- The NB works fine with WinNT and FreeBSD 3.5.1.
- Pls. remember: The VIA Southbridge VT82686A (Rev. 0x06) is not the
  VT82686_B_.
- The problem is independent whether I raise on the BSD slices more 
  filesystems (eg. /, /usr,..). Currently I have simply a swap and a /.

Fix: 

Simply stay with the old ATA-Drivers/FreeBSD Release.
How-To-Repeat: Simply reinstall 4.x on that Notebook.

Hmm, the '686A is supported in 4.3 so thats not the problem, you should
try to disable DMA on 4.3 and see if that solves the problem.

No feedback, and all current VIA southbridges are known to work.
