Hi... I just started testing 8-CURRENT and I have to say it really rocks. Is so incredibly fast (even with WITNESS activated). Great work!!! Currently I'm using 8-CURRENT within VMware workstation (6.0.4) and XEN (3.3.0) as para-virtualized domain. I've seen some kernel traps which appear on XEN and VMware, and some only on XEN or VMware. I've tried to collect them all, and saved them in the attached text-file. I'm currently running on SVN revision 187392. I'm experimenting for over a week now, and always seen the traps. How can I help resolve this issues? Since I'm experimenting in virtual machines it's no problem to test whatever needed. greetz olli XEN: ======================================== template-8_CURRENT# umount /mnt/new lock order reversal:
