https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274252 --- Comment #2 from Kyle Evans <kevans@freebsd.org> --- (In reply to Jason A. Harmening from comment #1) IIRC from the last time I debugged this, we actually get stuck just inside @ kmem_alloc_contig_domainset. kmem_alloc_contig_domain() does fail, but it's an M_WAITOK allocation so vm_domainset_iter_policy() just keeps restarting the search and we never break out. There's currently no way for, e.g., kmem_alloc_contig_domain() -> kmem_alloc_contig_pages() -> vm_page_alloc_contig_domain() to differentiate between a transient failure condition and an impossible request. -- You are receiving this mail because: You are the assignee for the bug.home | help
