Default Logout Causes Panic (Xorg #PF) Opensolaris nv_30

Have DELL Latitude D800 with nv_30 (OpenSolaris) using latest 'nvidia' binary. Login and select 'Command Line' rather than JDS or CDE session causes panic.

Login to JDS works reliably with 1680x1050 resolution...however logout causes panic (Xorg #PF). This problem goes away with 'nv' driver.

Performance with 'nvidia' driver (glxgears) is SO MUCH BETTER! I would prefer to correct this problem.

Would someone be interested in working Solaris x86 Crash Dump Analysis?

Problem seems to have somethiing to do with %esi = 0xdeadbeef and pollwakeup?

Default Re: Logout Causes Panic (Xorg #PF) Opensolaris nv_30

Is the problem specific to this OpenSolaris build?

Dont' think it is specific to this build. Updated from nv_28 to nv_30 today in hopes the problem would 'go away'. The problem went away in nv_28 when 'nv' driver was used...and there is similar behavior in nv_30.

It appears 'nv_ioctl_ctl+0x171: call +0x499fca0 <kmem_free>' might be involved...but I'm not familiar enough with the debugging tools.

I don't see nv_ioctl_ctl() in the output you included in your first post, please save the output of $c, $r when you see it and post it here. Did this problem happen with Solaris 10?
