>Description:
since i change my disk drive from 40 to 160GB (using / filesystem for most of it)

8 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 a: 308354671   4225024     4.2BSD   2048 16384 43504  # (Cyl.   4191*- 310098*)
 b:   4194304     30720       swap                     # (Cyl.     30*-   4191*)
 c: 312579695         0     unused      0     0        # (Cyl.      0 - 310098*)
 d: 312579695         0     unused      0     0        # (Cyl.      0 - 310098*)
 e:     30720         0     4.2BSD   1024  8192 15360  # (Cyl.      0 -     30*)


i can't dump(8) it. after about half of the dump i start getting such messages:


piixide0:0: unable to load xfer table DMA map for drive 0, error=22
wd0a: DMA error reading fsbn 7667817788 (wd0 bn 7672042812; cn 7611153 tn 9 sn 21), retrying

sector number is pure nonsense here (it's far too high). and dump doesn't work of course.


it worked well with 40GB drive
>How-To-Repeat:
try to dump big >100GB (i think) filesystem
>Fix:
no idea
