https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249966 --- Comment #7 from Warner Losh <imp@FreeBSD.org> --- (In reply to Hans Petter Selasky from comment #4) > Looks like there are still issues with CAM refcounts. Not as far as I know. I've not seen any ref count leaks in CAM in a long time that weren't related to "stuttering" devices that came and went many times quickly over the course of a few seconds. So this is Though sleeping in cam_free_sim() suggests that somebody hasn't kept proper book somewhere... Or that somehow we've missed a wakeup on the sim from cam_sim_release... If this is reproducible, I have some basic debugging tools that we can use with kgdb to look at the state of CAM to see if this problem is caught by one of the checks I have. -- You are receiving this mail because: You are the assignee for the bug.home | help
