[-- Attachment #1 --] Hi, I'm running -CURRENT from yesterday. In a futile attempt to make some use of my rusty RivaTNT card, I installed the nvidia kernel port, but it seems to be doing some weird stuff with memory. This appeared in the messages log: ... Oct 28 16:04:33 scienide kernel: malloc() of "32" with the following non-sleepable locks held: Oct 28 16:04:33 scienide kernel: exclusive sleep mutex dev.mtx_api r = 0 (0xc39d478c) locked @ /usr/ports/x11/nvidia-driver/work/NVIDIA-FreeBSD-x86-1.0-4365/src/nvidi a_subr.c:753 Oct 28 16:04:33 scienide kernel: malloc() of "32" with the following non-sleepable locks held: Oct 28 16:04:33 scienide kernel: exclusive sleep mutex dev.mtx_api r = 0 (0xc39d478c) locked @ /usr/ports/x11/nvidia-driver/work/NVIDIA-FreeBSD-x86-1.0-4365/src/nvidi a_subr.c:753 Oct 28 16:04:33 scienide kernel: malloc() of "4096" with the following non-sleepable locks held: Oct 28 16:04:33 scienide kernel: exclusive sleep mutex dev.mtx_api r = 0 (0xc39d478c) locked @ /usr/ports/x11/nvidia-driver/work/NVIDIA-FreeBSD-x86-1.0-4365/src/nvidi a_subr.c:753 ... And now, the fun part. After booting, if I try to unload the module I get the attached panic. I know the nvidia kernel is proprietary code and yada yada, but the problem seems to be in the open source part of the code, so I have some hope I can get to fix it with a little help :-) Cheers, -- Miguel Mendez <flynn@energyhq.es.eu.org> http://www.energyhq.es.eu.org [-- Attachment #2 --] Script started on Tue Oct 28 17:16:08 2003 GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.
