It started like this: I used 2.6.39 for a long time without problems. Then I updated to 3.6.6 and errors started happening ONLY after that big image windows.qcow2 3.2GB file was first accessed from QEMU. Then I tried copying that file to another partition (plain R4) to save it and when I opened that file from QEMU then that partition started to give me problems. I even tried to do it on clean new R4 partition and it crashed. So now every R4 partition that has that file accessed from QEMU give me new problems with inconsistencies. Using it from FAT32 works OK. Only thing I changed recently was changing from piix sata driver to ahci. > Got the same, and if yes, then it definitily seems to be an effect of the > problem with in-kernel(?) dcache corruption - the one which also results in > BUGs at 000000000000000e, assertion "nikita-2050" in jnode.c and so on... > > BTW (@Edward): none of the problems can be reproduced on my VM with exactly > same software configuration (copied root partition)... > > Regards, > Ivan.
