[Arthur Marsh]

Package: gnu-fdisk
Version: 1.1-1
Followup-For: Bug #463720


when I run gfdisk -l /dev/sda I get a segfault:

_llseek(3, 2146830336, [2146830336], SEEK_SET) = 0
read(3, 
"\353X\220MSWIN4.1\0\2\10(\0\2\0\0\0\0\370\0\0?\0\377\0\4\373?\0K"..., 
512) = 512
_llseek(3, 32256, [32256], SEEK_SET)    = 0
read(3, 
"\353<\220MSWIN4.1\0\2 at A\0\2\0\2\0\0\370\0\1?\0\377\0?\0\0\0\206"..., 
512) = 512
write(1, "\n"..., 1
)                    = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

The "other" fdisk, reports:

sfdisk -l /dev/sda

Disk /dev/sda: 1019 cylinders, 134 heads, 62 sectors/track
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
Warning: The partition table looks like it was made
  for C/H/S=*/255/63 (instead of 1019/134/62).
For this listing I'll assume that geometry.
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from

Please also note that I get lock-ups loading eata on 2.6.23 and later 
kernels, but can load eata on 2.6.18 and 2.6.22 kernels successfully.
