Below is the output from the lspci: 1st machine: 00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02) 2nd machine: 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) Both machines worked a few years with intel Xorg xserver, with /etc/modprobe.d/i915-kms.conf containing the line "options i915 modeset=0" Unfortunately last time Xorg removed support for usermode mode setting in intel xserver, and I had to change the above line to "options i915 modeset=1". After that, both machines during boot simply freeze (screen is blank, no access through ssh, so probably the machine is frozen completely). I tried to recompile the kernel with support for Intel agpgart and i915 compiled in the kernel but then the machine freezes even faster (no boot messages appear, screen gets black almost immediately after loading of the kernel). I've tried to investigate the logs, but no error messages are logged. Well, there is one warning in the logs, but the system worked with that warning for at least one year and it didn't cause any additional problems...: Oct 26 21:10:51 wzab kernel: Pid: 1010, comm: modprobe Not tainted 2.6.36 #1 Oct 26 21:10:51 wzab kernel: Call Trace: Oct 26 21:10:51 wzab kernel: [] ? warn_slowpath_common+0x78/0xb0 Oct 26 21:10:51 wzab kernel: [] ? intelfbhw_active_pipe+0x58/0x60 [intelfb] Oct 26 21:10:51 wzab kernel: [] ? intelfbhw_active_pipe+0x58/0x60 [intelfb] Oct 26 21:10:51 wzab kernel: [] ? warn_slowpath_null+0x1b/0x20 Oct 26 21:10:51 wzab kernel: [] ? intelfbhw_active_pipe+0x58/0x60 [intelfb] Oct 26 21:10:51 wzab kernel: [] ? intelfb_pci_register+0xc27/0xdc3 [intelfb] Oct 26 21:10:51 wzab kernel: [] ? intelfb_pci_register+0x0/0xdc3 [intelfb] Oct 26 21:10:51 wzab kernel: [] ? local_pci_probe+0xb/0x10 Oct 26 21:10:51 wzab kernel: [] ? pci_device_probe+0x61/0x80 Oct 26 21:10:51 wzab kernel: [] ? driver_probe_device+0x65/0x170 Oct 26 21:10:51 wzab kernel: [] ? pci_match_device+0xa0/0xc0 Oct 26 21:10:51 wzab kernel: [] ? __driver_attach+0x79/0x80 Oct 26 21:10:51 wzab kernel: [] ? __driver_attach+0x0/0x80 Oct 26 21:10:51 wzab kernel: [] ? bus_for_each_dev+0x52/0x80 Oct 26 21:10:51 wzab kernel: [] ? driver_attach+0x16/0x20 Oct 26 21:10:51 wzab kernel: [] ? __driver_attach+0x0/0x80 Oct 26 21:10:51 wzab kernel: [] ? bus_add_driver+0x177/0x230 Oct 26 21:10:51 wzab kernel: [] ? pci_device_remove+0x0/0x40 Oct 26 21:10:51 wzab kernel: [] ? driver_register+0x63/0x120 Oct 26 21:10:51 wzab kernel: [] ? __pci_register_driver+0x3d/0xb0 Oct 26 21:10:51 wzab kernel: [] ? do_one_initcall+0x32/0x160 Oct 26 21:10:51 wzab kernel: [] ? __vunmap+0xa8/0xe0 Oct 26 21:10:51 wzab kernel: [] ? intelfb_init+0x0/0x42 [intelfb] Oct 26 21:10:51 wzab kernel: [] ? sys_init_module+0x123/0xfd0 Oct 26 21:10:51 wzab kernel: [] ? sysenter_do_call+0x12/0x26 Oct 26 21:10:51 wzab kernel: ---[ end trace ec82370e7b0b3abd ]---
