Of those, I would only expect taking the hotspare out of the pool and using= the raw device for swap to provide a usable crash dump, but am not at the point= of recommending that you do so. > Did you take a look at the photo of the console? Does it seem interestin= g? It is 100% reproducable and the panic is instant. I did look at it, and it seems interesting, but unfortunately outside my ar= ea of expertise. Hopefully Andriy will take a look. --=20 You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.=
