Hi, I have todays CURRENT. My machine is Dell Latitude D620 with 945GM graphics card. When I try to run xorg 7.2, my machine hangs and on serial console it showed: uma_zalloc_arg: zone "64" with the following non-sleepable locks held: exclusive sleep mutex drm device r = 0 (0xc3c06cd8) locked @ /usr/src/sys/modules/drm/drm/../../../dev/drm/drm_drv.c:907 KDB: enter: witness_warn [thread pid 739 tid 100092 ] Stopped at kdb_enter+0x32: leave db> bt Tracing pid 739 tid 100092 td 0xc3fe2220 kdb_enter(c086100b,e63ea9fc,4,1,0,...) at kdb_enter+0x32 witness_warn(5,0,c08bd9fe,c08a71b1,66666666,...) at witness_warn+0x1b9 uma_zalloc_arg(c1072d20,0,102,2,c09d9d64,...) at uma_zalloc_arg+0x34 malloc(2c,c093d0c0,102,12,c4325db0,...) at malloc+0xd2 sysctl_add_oid(c4325dcc,c09d9d64,ffffffff,c4325db0,80000001,...) at sysctl_add_oid+0x95 alloc_bounce_zone(44,c09399e0,101,1000,c3c8ec80,...) at alloc_bounce_zone+0x16d bus_dma_tag_create(0,1000,0,ffffffff,ffffffff,...) at bus_dma_tag_create+0x1a9 drm_pci_alloc(c3c06c00,1000,1000,ffffffff,20000,...) at drm_pci_alloc+0xe1 i915_dma_init(c3bf3800,80446440,c4325e80,3,c3fe2220,...) at i915_dma_init+0x2b8 drm_ioctl(c3bf3800,80446440,c4325e80,3,c3fe2220,...) at drm_ioctl+0x357 giant_ioctl(c3bf3800,80446440,c4325e80,3,c3fe2220,...) at giant_ioctl+0x56 devfs_ioctl_f(c3e70048,80446440,c4325e80,c405c500,c3fe2220,...) at devfs_ioctl_f+0xc9 kern_ioctl(c3fe2220,8,80446440,c4325e80,0,...) at kern_ioctl+0x243 ioctl(c3fe2220,e63eacfc,c,c089e511,c0935830,...) at ioctl+0x134 syscall(e63ead38) at syscall+0x2b3 Xint0x80_syscall() at Xint0x80_syscall+0x20 --- syscall (54, FreeBSD ELF32, ioctl), eip = 0x483decc3, esp = 0xbfbfea5c, ebp = 0xbfbfea78 --- db> db> c uma_zalloc_arg: zone "16" with the following non-sleepable locks held: exclusive sleep mutex drm device r = 0 (0xc3c06cd8) locked @ /usr/src/sys/modules/drm/drm/../../../dev/drm/drm_drv.c:907 KDB: enter: witness_warn [thread pid 739 tid 100092 ] Stopped at kdb_enter+0x32: leave db> thanks, Ganbold -- Inspiration without perspiration is usually sterile.
