this looks like a userspace program accessing some mmap-ped data, which is triggering a dbe. The first question is which application is it ? My first thought was an X server, but I don't even know, if there is one for the O2. What program are running, when the machine crashes ? > > Got dbe at 0x2ac2bffc > > [...] > > Index: 20 pgmask=4kb va=0007fd06000 asid=6b > > [pa=0000c67b000 c=3 d=1 v=1 g=0] [pa=000032bf000 c=3 d=0 v=0 g=0] > > Index: 21 pgmask=4kb va=0002acf0000 asid=6b > > [pa=0000d1c1000 c=3 d=0 v=1 g=0] [pa=0000c188000 c=3 d=0 v=0 g=0] > > Index: 25 pgmask=4kb va=0002acf0000 asid=6b > > [pa=0000d1c1000 c=3 d=0 v=1 g=0] [pa=0000c188000 c=3 d=0 v=0 g=0] > > Index: 41 pgmask=4kb va=0002aac8000 asid=6b > > [pa=0000368e000 c=3 d=0 v=0 g=0] [pa=000506c0000 c=3 d=1 v=1 g=0] these are the only TLBs which are user space. What looks strange to me is Index 21 and Index 25. Both are mapping the same page. Looking at the R4600/4700 manual (didn't have a R5k manual handy) indicates no problem with duplicate TLB entries. I can't check, if pyhsical addresses are correct, because I don't know how memory is mapped. I need to see the CRIME MC messages from bootup. Even better is a complete boot log.
