Description Chris Collins 2010-11-24 12:00:24 UTC

This machine is patched up to zfsv15 which may be very relevant.

If I change to a .zfs dir on any fileset eg. I have tank/home mounted on /usr/home so cd /usr/home/.zfs, and then run ls with colors it causes a kernel panic.

gnuls -a --color=always = panic
ls -aG = panic
ls = no panic

not tested gnuls with no colors and not tested 'ls -a', is a production server so I will need to wait until night for further testing.

no kernel dumps yet as no dumpdev configured, if using a zfs swap partition is safe (used in fstab) as a dumpdev I will configure it and repeat.

Fix: 

a workaround is just run plain ls, of course this means if usually alias ls then it needs to be unaliased.
How-To-Repeat: cd /usr/home/.zfs (edit to path to .zfs dir)
ls -aG

I'm doing a bunch of tests over this problem, I'm gonna figure out if it 
was solved and will address this PR to the right person once again.
