Yes, still present. I did this on my Fedora 15 system with 3.1.0-rc9+ (git pull as of half an hour ago): echo -n reboot > /sys/power/disk for (( i=0; i<15; i++)); do pm-hibernate; sleep 2; done With nomodeset passed into to the kernel, the cycle finished successfully. There was one program that segfaulted (modem-manager) in one of the cycles only. I'm guessing this is probably a bug in the program. Without nomodeset (i.e. KMS), I got corruption and "unable to handle paging request", followed by kernel hang on second thaw. It's pretty much what happens when corruption occurs. PS. Kernel 3.1.0-rc9+ was patched with my own hibernation patch that calculates CRC32 of image pages on hibernate/thaw, so the chances that what was read in was not what was hibernated were minimal. You can find it here: http://marc.info/?l=linux-kernel&m=131820444524522&w=2. I'm experiencing the same with Fedora supplied kernels (i.e. 2.6.40.6-0.fc15.x86_64, which is really 3.0.6). -- Bojan _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
