Subject: LTP: list of failures on 32bit and compat mode
Following LTP syscalls failed on the i386 and arm environments with
Linux next / mainline kernels. The userspace is coming from Open
Embedded kirkstone.
Anyone seeing this problem on 32-bit i386 or arm ?
You get to see "segfault" in the following logs that have been noticed
on i386 only.
This is not a new problem. We have been noticing these failures for a
really long time.
Would it be worth investigating the reason for failures on 32bit architectures ?
