Whatever.) That's a lot of stuff that happened right before this last print macro. Maybe ages were spent in hpsb_selfid_complete. I will try to work on getting non-critical parts out of hpsb_selfid_complete issue during the week, but I don't know how fast I can do this and if this will help in the first place. ... > I didn't mention that I have: > > options ieee1394 disable_nodemgr=1 > options ohci1394 phys_dma=0 > > in my /etc/modprobe.conf.

Posted writes are still enabled. phys_dma=0 disables only the physical response unit. You have to change the source if you want to disable posted writes. See the top of ohci_initialize.
