Hi folks, running at RELENG_6. I've csup'ed and rebuild kernel + world on 2006-09-03 and again on 2006-09-05 because of some trouble (panics related to altq). Because I've experienced some panics (well... not really me who does panic), my gmirror RAID-1 is causing trouble since the kernel + world build done at 2006-09-05. This issue hasn't been experienced with my 2006-09-03 build. Now the issue: The system panics (not related to this problem). Because of the panic, my gmirror RAID-1 is going out of sync. When the machine comes up again, gmirror tries an automatic syncing of the mirror(s). As soon as this is starting, the machine is blocking (keyboard input is ok as long as I'm not going to do something disk-consuming). `gmirror status' says it's rebuilding but in fact there's no disk activity and the HDD LED is constantly ON. The only way out is sometimes CTRL+ALT+DEL, sometimes I need to break to debugger and hard-reset the system. The only way out of this machine freeze is to startup into su-mode, deactivate/remove some gmirror providers and run in degraded mode all time. The machine also does freeze in su-mode as soon as I'm manually trying to re-sync the mirror. So I think I've made sure it's really a gmirror problem. I've seen there have been some cvs commits between 2006-09-03 and 2006-09-05. Are there any changes to take note of? Any configuration changes which I should have done? I'll now go on and rebuild kernel (already done) + world with freshly csup'ed sources, reboot and test once more if gmirror freezes again (will take an hour). Running gmirror with four slices (gm0s1: ad4s1, ad6s1; gm0s2: ad4s2, ad6s2 etc.).
