Hi Geert,
how easy is that to reproduce?
sd_setup_read_write_cmnd() does not validate the request's FUA flag
against sdkp->DPOFUA (not suggesting that it should ...). I'd like to
try and trace when such a mismatch happens.
Cheers,
Michael

Peculiar. That write command looks OK to me. I wonder if it's the FUA
bit that trips it?
What does:
# dmesg | grep FUA
say?
sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't
support DPO or FUA
