[OpenIndiana-discuss] /hisper: latest upgrade caused Xorg to die (coredump)

[Predrag Zečević - Unix Systems Administrator]

Hi All,

I have strange situation when tried to update BE for currently running:
SunOS Release 5.11 Version illumos-cb3c687 64-bit
to latest one:
SunOS Release 5.11 Version illumos-e2af1b5 64-bit

When tried to boot int new BE, Xorg has dumped core:

$ pstack core.Xorg.1934  |less
core 'core.Xorg.1934' of 1934:  /usr/bin/Xorg :0 -seat seat0 -auth

Xorg.0.log contains nothing suspicious; /var/adm/messages too. So, not 
sure from where to start. System was booted, but w/o GUI - most of 
services were set to offline.

I was forced to boot into old environment. Does anyone has clue what 
could be cause (no H/W was changed - just BE updated and tried to boot).


dbx complained:
...
dbx: core file read error: address 0x80c48348e5894855 not in data space
...

mdb gave some output too:
$ mdb core.Xorg.1934

Are there better tools to analyze core file?
