Hi,
I'm trying to get OpenBSD to run on a HP Pavilion g7-2010nr (Intel Core3) 
laptop.  OpenBSD installed (i386) from the install CD (i.e. it is able 
to mount the CD and load the sets) but the generic 5.1 kernels (both SP 
and MP) are unable to access the CD (and show an error in dmesg).  The 
generic 5.2-current kernel recognizes the CD (no dmesg error) but is 
unable to read data from the cd0.

Under the 5.1 release, the CD is not recognized (dmesg extract, full 
dmesg at the end of the message):

   cd0 at scsibus0 targ 4 lun 0: <hp, CDDVDW SN-208BB, HH03> ATAPI 
5/cdrom removable vendor "Intel", unknown product 0x1e22 (class serial 
bus subclass SMBus, rev 0x04) at pci0 dev 31 function 3 not configured

I substituted the 5.2-current kernel:

    OpenBSD 5.2-current (GENERIC.MP) #27: Fri Sep 21 04:00:49 MDT 2012

and it recognizes cd0, but the CD can't actually transfer data.  The 
dmesg extract (full dmesg at the end of the message) shows cd0 as OK:

   cd0 at scsibus0 targ 4 lun 0: <hp, CDDVDW SN-208BB, HH03> ATAPI 
5/cdrom removable bufq_init, hi 64, low 32

I can tell the CD isn't working because disklabel shows a bogus label:
   c: 400000 0 unused

and I can't even dd from the c partition:

# dd if=/dev/cd0c of=cd.img bs=512 count=2
  dd: /dev/cd0c: Input/output error
  0+0 records in
  0+0 records out
  0 bytes transferred in 0.000 secs (0 bytes/sec)

Interestingly, I can eject the disc with "eject cd0"

Thanks for any help,
Don
