Hi Colin, That looks one progress, but still takes time to reproduce that, and I will use your new approach to reproduce that.
When you are doing that, could you dump the file of /proc/$(pidof irqbalance)/maps so that we can see where the faulted address are in the process's vm space? thanks, On Sat, Jul 4, 2015 at 4:10 AM, Colin Ian King <1469...@bugs.launchpad.net> wrote: > Running the following: > > #!/bin/bash > tests="affinity aio bigheap brk bsearch cache chdir chmod clock context cpu > crypt dentry dir dup epoll eventfd fstat fallocate fault fifo flock fork > futex get getrandom hdd hsearch inotify io itimer kcmp kill lease link lockf > longjmp lsearch malloc matrix memcpy memfd mincore mlock mmap mmapmany mremap > msg mq nice null open pipe poll procfs pthread qsort readahead rename rlimit > seek sem sem-sysv sendfile shm-sysv sigfd sigfpe sigq sigsegv sock splice > stack str switch symlink sysinfo sysfs tee timer timerfd tsearch udp > udp-flood urandom utime vecmath vfork vm vm-rw vm-splice wcs wait yield xattr > zero zombie" > > for t in $tests > do > echo $t > echo $t > /dev/kmsg > ./stress-ng --$t 0 -v -t 60 > done > > eventually tripped the translation fault in irqbalance.
