xorg started segfaulting here on startup, at the point where it should |
| 2 |
detect input devices: |

For reference, here's the same location in a good start: |

So it's segfaulting in libudev. And where it's getting weird is that it |
| 43 |
only segfaults if I have one particular encrypted container mapped. The |
| 44 |
container is a file mapped to /dev/loop0, opened with "cryptsetup |
| 45 |
luksOpen" as "/dev/mapper/crypt-morpheus.athome". If I "luksClose" it |
| 46 |
(but keep /dev/loop0), xorg starts normally. |
| 47 |
|
| 48 |
Strangely, there is another encrypted container "/dev/mapper/crypt-swap" |
| 49 |
mapped to my swap partition, but that one doesn't seem to interfere. |
| 50 |
|
| 51 |
This symptom has only started today, and I haven't updated anything |
| 52 |
udev- or xorg-related. However, I reboot rarely, and I did reboot today, |
| 53 |
so it may be due to an earlier update. |
| 54 |
|
| 55 |
Some version info: |
| 56 |
|
| 57 |
xorg-server-1.8.1.901 |
| 58 |
xf86-input-evdev-2.3.2 |
| 59 |
udev-149 |
| 60 |
gentoo-sources-2.6.31-r6 |
| 61 |
|
| 62 |
Has anyone seen anything similar? Any idea how I could either work |
| 63 |
around the issue or debug it? I have tried strace but couldn't extract |
| 64 |
any meaningful information. |
