Yep, I noticed that, too. IIRC a bug like ``kmem_free(NULL, size)'' somewhere in the kernel can have the effect that a subsequent ``kmem_alloc(size, KM_SLEEP)'' somewhere else in the kernel will return with a NULL pointer! (Assuming you run release bits) For that reason I did suggest to Kyle to try to reproduce this hsfs mount panic with kmem heap checking enabled. Add the following line to /etc/system, reboot, retry to reproduce the hsfs mount panic: set kmem_flags=0xf _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
