Hi,

I'm trying to get suspend/resume to work on my sony vaio (PCG FX-140)
laptop.  Everything works fine if I run the X server without
acceleration enabled in xorg.conf.  But if I run it with acceleration
turned on, then I get either X server crash on resume or sometimes even
hard freeze(sysrq does not work).  The graphics chipset is Intel 82815
and so it uses i810 driver.

I'm running 2.6.11 with cko5 patches including software suspend2
(2.1.7.2) patches.  This is true with both 6.8.2 and the latest cvs pull
of Xorg server.

I see the following output in logfile after the crash :

Error in I810WaitLpRing(), now is 24848, start is 22847
pgetbl_ctl: 0xf4d0001 pgetbl_err: 0x0

memmode: 4 instps: 850
hwstam: bac7 ier: 0 imr: bac7 iir: 0
space: 65464 wanted 65528

Fatal server error:
lockup


Further attempts the start the X server (with or without acceleration)
result in same output. Even system restart(power cycling) does not help.
The only way to get X server to run is to power down the laptop and
switching it back up.

I'm attaching pruned X server log and lspci output.

Any lead would be greatly appreciated.

regards,

-Wilson
