Hello, i'm using linux 2.6.0-test11-bk11 on Intel architecture (Celeron Coppermine) and nvidia kernel module 1.0-4620 for Nvidia GF FX 5200. Mttr registers are enabled. I applied appropriate patches from www.minion.de. After loading and using nvidia kernel module, dmesg shows this output: nvidia: module license 'NVIDIA' taints kernel. 0: nvidia: loading NVIDIA Linux x86 nvidia.o Kernel Module 1.0-4620 Mon Sep 29 08:49:59 PDT 2003 Debug: sleeping function called from invalid context at mm/slab.c:1856 in_atomic():1, irqs_disabled():0 Call Trace: [] __might_sleep+0xac/0xe0 [] kmem_cache_alloc+0x67/0x70 [] __get_vm_area+0x21/0x100 [] get_vm_area+0x33/0x40 [] __ioremap+0xc2/0x120 [] ioremap_nocache+0x29/0xb0 [] os_map_kernel_space+0x4c/0x80 [nvidia] [] __nvsym00566+0x1f/0x2c [nvidia] [] __nvsym00753+0x6e/0xe0 [nvidia] [] __nvsym00759+0x1e/0x190 [nvidia] [] rm_init_adapter+0xc/0x10 [nvidia] [] nv_kern_open+0x127/0x240 [nvidia] [] chrdev_open+0xf4/0x220 [] dentry_open+0x14b/0x220 [] filp_open+0x66/0x70 [] sys_open+0x55/0x90 [] sysenter_past_esp+0x52/0x71 Debug: sleeping function called from invalid context at mm/slab.c:1856 in_atomic():1, irqs_disabled():0 Call Trace: 118c0c>] __might_sleep+0xac/0xe0 [] __kmalloc+0x89/0x90 [] os_alloc_mem+0x7c/0xa0 [nvidia] [] __nvsym00082+0x10/0x24 [nvidia] [] __nvsym04313+0x10/0x14 [nvidia] [] __nvsym03556+0x4a/0x1f0 [nvidia] [] __nvsym01940+0x46c/0xf20 [nvidia] [] mempool_free+0x50/0xb0 [] mempool_free+0x50/0xb0 [] __nvsym03624+0x106/0x110 [nvidia] [] __nvsym03626+0x0/0x54 [nvidia] [] __nvsym03626+0x0/0x54 [nvidia] [] __nvsym02598+0x4f/0x6c [nvidia] [] __nvsym02635+0x277/0x2b4 [nvidia] [] __nvsym00842+0x6d/0xa0 [nvidia] [] __nvsym00758+0x77/0x224 [nvidia] [] __nvsym00751+0x1c/0x5c [nvidia] [] __nvsym00759+0x11b/0x190 [nvidia] [] rm_init_adapter+0xc/0x10 [nvidia] [] nv_kern_open+0x127/0x240 [nvidia] [] chrdev_open+0xf4/0x220 [] dentry_open+0x14b/0x220 [] filp_open+0x66/0x70 [] sys_open+0x55/0x90 [] sysenter_past_esp+0x52/0x71 agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode This always is happening on loading this module. I get same trouble with nvidia kernel module 1.0-4496. I never had such problems with kernel 2.4 before. Any suggestions? With best regards, Lukas
