[Crash-utility] another crash failed to start on SN vmcore
Hi Dave,
I have another vmcore that gdb (6.4) was able to display bt
but crash failed to come up. This copy of crash contains
the changes you suggested on my previous failure report (10/26).
I am not sure if this was caused by the fault of this vmcore, since
gdb only showed one thread. There should be another thread. But i
think i should let you know and let you decide if this is the
case.
Thanks,
- jay
