 |
|
was trying to dump my partition tables using sfdisk -d /dev/sdX sdX.out and got an error:
| Code: |
sniffer root # sfdisk -d /dev/sda sda.out
sfdisk: seek error: wanted 0x0000000000000000, got 0x0000000000000000
/dev/sda: unrecognized partition table type
No partitions found |
So tried to list partitions using sfdisk -l and got this collection of errors:

Anyone else having the same problem? Was using sys-apps/util-linux-2.12i-r1. Upgraded the package to 2.12p and 2.12q with same errors present. sfdisk -g works fine
| Code: | sniffer util-linux # sfdisk -g
/dev/hda: 79408 cylinders, 16 heads, 63 sectors/track
/dev/sda: 17849 cylinders, 255 heads, 63 sectors/track
/dev/sdb: 2213 cylinders, 255 heads, 63 sectors/track

AFter some searching, appears to be related to gcc 3.4. Should affect all Jackass project users.

Initial Package Version: 2.12b
Upstream Status: Not submitted - fixes GCC miscompilation
Origin: Created from troubleshooting on IRC
Description: When using GCC 3.4.{1,2}, the sfdisk program is miscompiled,
causing a seek error to be output. Troubleshooting narrowed the problem down
to the fact that Util-Linux by default uses the -O2 optimization level,
which includes the unit-at-a-time optimization, exposing this problem. This
patch passes -fno-unit-at-a-time to the sfdisk, fdisk, and cfdisk programs,
resolving this error. Developed by Matthew Burgess, Ronald Hummelink, and
Jeremy Utley.

Any chance of fixing this in the util-linux packages? |

Here's the link to the Bugzilla post
https://bugs.gentoo.org/show_bug.cgi?id=79454
Short version...
After many recompiles to test. It's the -O3 optimization that seems to cause the problem with sfdisk mentioned above. Backing off to -O2 with all other Jackass optimizations solves the problem. Sorry, don't know how to get that into the ebuild for just sfdisk as the rest of the util-linux package doesn't seem to care. This bug affects util-linux 2.12i 2.12p and 2.12q the same way. |
