Hi,
I have been testing a scratch filesystem, with soft updates journaling enab=
led.
I have been seeing one of these two panics:
panic: ino 0xc5d0f600(0x3C8209) 14147, 7047 !=3D 14098
and
panic: Bad link elm 0xc4d7cd00 prev->next !=3D elm
If I disable soft updates journaling, I do not see these panics.
