Hehe, you have nice testcase for xfs now :-).

Should've, I guess, hd is large enough anyway. > > Half of the time I'll be told by the softlockup watchdog that it locked > > up, but sometimes it actually works, that is, it suspends and resumes. Obviously that was phrased wrongly -- the code hangs and the softlockup watchdog indicates it. But I don't know why. Can writing the MSR hang? > I believe this is gone in -git kernels for some other reasons. I'm not even sure the hack I did there with marking the area as nosave is good. At the very least the code shouldn't live in the MPIC file since the code reserving the chunk doesn't either. What about the page_is_ram() part? Doesn't any other platform have a RAM hole between 2 and 4 GB? Or is that handled more generically with discontig support? (and if yes, how does discontig support work?) johannes --=-/fHW3lXz/wGv10x8BYpy Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIVAwUARKP+nqVg1VMiehFYAQJnMw/9GXmZK1ql/5NzKO3gM5yJvPyIBjpCBkFH 0M3iCeohIVXGx3tScdMSDZamqSLotdsBGI7JqI+pWFFC+NVlTkrVIUGB/iX98aeI BC+tXlWr4xY7VIm+E9SCzfAMyYc+6GXTejS6n3umVVpl9sd9sb9r5s1mYIaDa+ZF NYmN0GV9EpIT/c9/rA9k0ueWUP/5w66KoKVuFPGqfLiA77bOA9GgAzPevgmCNPiQ Lqa4+ExLJbCxZIFW15Xrz1VCh9GSw/Pvam3h3z11olRpKSs+DzlLHEC9svBjQs7H TFym3QLnZPjffIEKczPOoNDHWe4LQUysVHGn4D15U97mbuW9ObuKjO3eUk29duYq ElagSUfXdwJKMAIizD0mPedbYCMPBqEVpPPZG5lM/NDJMIfGJVFMzyzzqNhL+8pM lVXhIuiP0Pgj76E7agGLYaGB2K1ENrZlybxpTxvTVP9uwXfad+Vq1cHI9cGTIroH edaC2NcC6HQF1Stt9SWqYgfeWA+Z58DJMuDt9+qdwFK5lDdwdSCREa/35Gps8VZb UebsLDU5RfMv2Lcm8pzqAsGvr1a7wlZwu+pyqR4H3XGHhcToVRBZRYgeG/6A9HYZ YDIwCbzoL7Eeoyj69SyEQiz4rtL7Sgjre+76BacA4GWS2ZbfejheGLDmxp+N55M5 FyQ/9dkyxrs= =zJ7e -----END PGP SIGNATURE----- --=-/fHW3lXz/wGv10x8BYpy--
