15 where find:
16
17 "which means, with SANITIZE: crash, w/o SANITIZE: no work..."
18
19 And also my recall in the next comment, the c57 of how previously even
20 the SANITIZE-disabled kernel crashed.
21
22 Wish I could dedicate more time to that testing now... Unfortunately,
23 no straight dedicated long enough time to work on that available here
24 for one or two more days...
25
26 Binary search should be in order...
27
28 And your reply in that bug, to how that different behavior of those
29 kernel, for non-experts would be great... (the "ioctl(KVM_CREATE_VM)
30 failed: 12 Cannot allocate memory"... by SANITIZE-disabled kernel...
31
32 Of course, if you can find that time... (esp. since I can not find much
33 time now for a while)...
