I have similar messages since -git1 System: Debian sid/experimental Compiled as: x86_64 SMP preemptible CPU: Intel Dual Core E2200 Fixed for me in -git11. Jean-Luc, please test fresh snapshot It is fixed for me in -git12, I've not been able to boot -git11: I've a lvm over raid1 and with -gitxx, and sometimes the device numbering is not consistant from one session to the other. Well, this ticket should be closed as I think. But I have no experience with bugzilla... seems only creator can modify ticket status? I've closed it with code_fix. Tell me if appropriate. Thanks, Jean-Luc! |
