hp nc6230 ad0 timeout errors.

[brad miele]

hi,

I have a hp nc6230 that has run freebsd in the past. I am trying to 
install 6.2, and the install from CD goes fine, but it will not make it to 
a login prompt on a subsequent reboot. The error is:

  ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=2270335
  g_vfs_done():ad0s1a[READ(offset=1162379264, length=49152)]error=5
  vnode_pager_getpages: I/O read error
  vm_fault: pager read error, pid 46 (sh)
  pid 46 (sh), uid 0: exited on signal 11

then it drops me to single user, but that doesn't work and the machine 
starts streaming the ad0 errors past me. In the past I have always 
assumed that this is a drive going bad, however i have tried it with 3 
drives to the same effect. One of the drives has a windows partition that 
has no issues.

The bios on the laptop is the latest.

I am going to see if i can adjust the UDMA mode at boot with atacontrol. 
Any other advice would be great. Sorry if this is the wrong list and 
whatnot.

Brad
