Hello,

I hit same problem before. We have discussed this issue with Vincenzo Maffi=
one.=20
He told me that ixl driver has issues but setting
hw.ixl.enable_head_writeback=3D0
on loader.conf helps.
By setting this loader tunable I solved my problem.

I hope it helps to you also.

It will be good if this issue could be solved within ixl driver.

Regads
Ozkan
