g_vfs_done errors in CURRENT

not sure what is going on here, but i thought i should report it.  6.0 
seems to work OK.  but with CURRENT, i get these about 2 minutes after 
rebooting:

Mar 18 13:49:07 springfield kernel: 
g_vfs_done():ad0s1f[READ(offset=8796014739456, length=16384)]error = 5
Mar 18 13:49:08 springfield kernel: 
g_vfs_done():ad0s1f[READ(offset=8796014739456, length=16384)]error = 5
Mar 18 13:49:08 springfield last message repeated 2 times

dozens of 'em, and then the system panics.  no core dump.

pciconf is attached.... the file system lives on the IDE drive, which is 
a fairly new Seagate.  i replaced an ancient IBM Deskstar thinking i had 
hit a bad block, but the error with the new drive is the same.

the southbridge on this mainboard (Tyan 250x) is known to have IDE issues.
