Hi again,

as I can see you wrote the SATA driver for Pmac, you may have an idea of
what going wrong on the Imac.
I did activate DPRINTK and VPRINTK in libata and added a few messages.
It seems that the SET_FEATURES command never completes. So the insmod
stays blocked but the machine is still fully usable from another shell.
I attach here the complete dmesg I got when booting.
Please note that the message:
"ata_dev_set_xfermode: qc_issue xfer_mode=12" used to be "... xfer=70"
(note the printk I added is decimal) but I tried to force it to the
xfer_mode I saw from  ata_host_set_pio trace, and it changed nothing.

Regards.
