I cvsupped this evening at 19:34 UTC. The new ULE scheduler works fine
in single-user mode (it survives "make kernel"), but when I go to
multi-user mode I get a "sched_add: trying to run inhibited thread"
panic (2 vmcores lost due to fsck :( )
This is on a SMP dualcore Intel T5600 laptop (dmesg + kernelconfig attached)
Could it be caused by some user process (pgsql / boinc) ?
Well, at least the 4BSD continues to run...
Regards,
Rene
