--- Comment From bren...@br.ibm.com 2018-04-30 15:20 EDT---
I tried to reproduce this on my machine and I was not able to. I am using 
kernel 4.15.0-20-generic and I run:

# ltp-install  pwd
/home/breno/ltp-install

# ltp-install  sudo ./runltp

Is there any other way to reproduce it?

@Pavithra: can you validate and see no longer you observe assert issue
and as per dev. suggestion you can open a new defect on crash issue.

--- Comment From dougm...@us.ibm.com 2018-04-19 06:51 EDT---
There are two different panics being shown here. One is the kernel assert in 
usercopy.c, the other is the crash in qla2xxx. You should not be using one bug 
to handle two different issues. If the kernel assert is no longer happening, 
then close this bug.

--- Comment From dougm...@us.ibm.com 2018-04-17 13:13 EDT---
The logs show some "read_all" process - presumably part of the test suite - 
that is trying to read kernel text memory (via /dev/mem) and triggering the 
BUG. Not clear if the attempt should have been failed gracefully or not. I'd 
assume the expectation is that a illegal read from /dev/mem should return an 
error rather than panic.

Comment #21 shows a different panic, and since no logs or vmcore are
provided I can't tell any more about it. If this latest panic is the
only reason the bug is open, we need to move that to a new bugzilla as
it is not the same issue.

--- Comment From dougm...@us.ibm.com 2018-04-17 13:15 EDT---
Comment #19 also shows a different issue than originally reported. So, it seems 
this bugzilla has deviated from the original problem.

--- Comment From dougm...@us.ibm.com 2018-04-17 09:47 EDT---
Note, the logs are showing a kernel assert (BUG), not a crash. The assert is 
that something is wrong with the address/length being used to copy data in/out 
of userspace. We need to look closer at what is being done by the test suite.
