The bios is not detected, this is the initial problem that needs solving. Created attachment 11523 [details]
Xorg.0.log
Today, a freshly compiled nouveau_drv.so gives me a new crash.
I uploaded a new log from the latest nouveau_drv.so. The new crash is: /usr/lib/xorg/modules/drivers//nouveau_drv.so(nv30UpdateArbitrationSettings+0x23) [0x2ac7262f1823] 4: /usr/lib/xorg/modules/drivers//nouveau_drv.so(NVCalcStateExt+0x41c) [0x2ac7262f277c] 5: /usr/lib/xorg/modules/drivers//nouveau_drv.so(NVDACInit+0x44f) [0x2ac7262ea60f] 6: /usr/lib/xorg/modules/drivers//nouveau_drv.so [0x2ac7262ee5d5] 7: /usr/lib/xorg/modules/drivers//nouveau_drv.so [0x2ac7262f002c] 8: /usr/lib/xorg/modules/drivers//nouveau_drv.so [0x2ac7262f050a] 9: /usr/bin/X11/X(AddScreen+0x222) [0x439522] 10: /usr/bin/X11/X(InitOutput+0x268) [0x468a48] 11: /usr/bin/X11/X(main+0x275) [0x439d25] 12: /lib/libc.so.6(__libc_start_main+0xf4) [0x2ac72413bb44] 13: /usr/bin/X11/X(FontFileCompleteXLFD+0x229) [0x439209] it seems to involve the nvGetClocks call in line 694 in nv_hw.c. Digging into nvGetClocks, the crash happens at line 191 where *MClk is computed:
*MClk = ((N * NB * pNv->CrystalFreqKHz) / (M * MB)) >> P;
In my case, pll had the value 0x0b01, causing MB to evaluate to zero, thus causing a divide by zero error.

xorglog after patch applied
Latest nouveau updates from nv makes this bug obsolete (I now get X up on the screen, although somwhat garbled) I had no valid modes by default on my Thinkpad R61 (neither 1680x1050 internal or standard external 1920x1080p was working by default). The only way to start X up was to feed it manually generated modelines. |
