What happened to this once very stable kernel? I am hitting panic after panic
with basic things which worked fine before.
I upgraded from 134 to get rid of panic which happened when invoking 'ps' or
'top' or any other utility which used procfs. And now this! I haven't hit a
kernel oops even in an RC1 of Linux kernel release.
PS: Unrelated issue: 'zpool import' was core dumping. After much trussing, I
found that I needed to do 'devfsadm -C' to clean up dangling devices nodes. Why
is that cleanup not done by the boot scripts by default?
