Is this because the system default to async ? Ok, let's get this clear: 1.new kernel, latest sources, latest softupdates on P5-133 x 2 / 7880 UW onboard Adaptec, 4Gb UW. Note: /tmp and /pub were mounted async. NOT /usr/src. i.e.: /pub async only /tmp async only /usr/src softupdates only - make -j4 buildworld. 3 minutes -> PANIC 2.I reboot, fsck^H^H^Hnewfs /usr/src & untar a clean source backup - I mount everything "normal" (no sync, no async specified), but /usr/src is softupdate'd: make -j4 buildworld. It's been running for 40 minutes so far. No glitch. Observations: It looks like mounting async _other_ FS'es than a softupdate one still causes panics -- this wasn't explicit in the last messages. AHC_TAGENABLE and AHC_ALLOWMEMIO no good for me (SCB lockups, couldn't even break into the debugger). -- -[ Philippe Regnauld / sysadmin / regnauld@deepo.prosa.dk / +55.4N +11.3E ]- «Pluto placed his bad dog at the entrance of Hades to keep the dead IN and the living OUT!
