Hi, this is related to a bug in 46 bit kernel, as you can see in https://bugzilla.kernel.org/show_bug.cgi?id=42977.
This issue is not solve, but there is a workaround, adding "nox2apic" to Linux boot. I change /etc/default/grub from GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nox2apic" This way I'm able to suspend/resume without problem. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/962142 Title: 12.04: Toshiba Tecra R840 fail to resume after suspend Status in The Linux Kernel: Incomplete Status in “linux” package in Ubuntu: Incomplete Bug description: Trying to resume from suspend fail. The only activity in the laptop is the cooler fan that seems to be put to maximum. There are no caps lock binking, no disk activity. Then display stays black. Then /var/log/pm_* don't shoes nothing special (no error on suspend, no messages on resume). I have to restart the computer. I try pm-suspend and s2ram, the results are the same. Suspend/resume works well with 11.10. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
