I guess we should look at the packet l= ength in vmbus_chan_recv(). A stack trace would also be useful. Annoyingly, I cannot reproduce it anymore. Must have been a glitch. > But, does it happen at all with the patch in comment 3? No, that fixes it for all memory sizes. > The attached patch should also eliminate unnecessary bouncing on i386 sys= tems with physical RAM above 4GB. I applied this latest one instead, and it also boots fine with different me= mory sizes. --=20 You are receiving this mail because: You are the assignee for the bug.=
