Netscape (32-bit) locks machine

I am running into an issue where Netscape will often lock up the entire machine when launched. It isn't just the X Server crashing, the entire system is frozen. This happens on both Rage 128 and Rage XL. On the Rage XL, I virtually eliminated the lock ups by removing latin2 fonts from my XF86Config file. With the Rage 128, nothing seems to help, including using option "noaccel" for the driver. We are using XFree 4.0.1 with patches (essentially the same patches that were just posted.)

Could be a bug in one of the font renderers. I know the FreeType
renderer has some bugs.Ummm. Looks like there are similar problems with the latest builds on ia32.
After doing some further testing, I have found that X seems to lock the machine hard on our Lion boxes pretty much all the time. Just starting X will sometimes lock them up. These boxes are all using the r128 driver.

I am going to try the latest code from CVS tomorrow and see if there is any improvment. If not, what can I do to help track down where the problem is coming from?
Well, on the assumption that it is a font renderer problem, you can try whittling down your font path until the problem stops happening. Start by removing TrueType (or clone), then Type1, Speedo, etc. If your running xfs, get rid of it first.
I went ahead and cut down my fonts to pretty much nothing. The problem still occurs. I turned off acceleration on the Lion boxes, and that allows our install program to run without X crashing. With acceleration turned on, the machine will hang if you use a scroll bar to move through a large text list.
It was pointed out to me that /dev/mem needs to be opened with O_SYNC, so that it will not be mapped write-cache. Mapping it with write cache can cause lockups. I have a patch applied in os-support/lnx_video.c that fixes this problem, but I still get lockups. I was wondering if there are any other places in the code where this could be happening?

/dev/mem was already being opened with O_SYNC in lnx_video.c.
Mark.
Mike-
I must have been asleep since I don't remember seeing the original message.
If your machine is crashing when running Netscape I would be suspicious of Netscape before I'd blame the X server. I just discovered a few weeks ago that you have to put the system in trickle' mode if you want to run IA32 programs, including Netscape, reliably. I understand you can set trickle' mode on the Lion BIOS. For BigSur's there's a patch for the kernel you can get from Intel to do this (I can't send you the patch, you need to send a message to `[email protected]' if you want it).
I hope this helps.

No, you weren't asleep. The original message only went to the XFree list, but I wanted to broaden the audience a little bit.
The problem is not restricted to netscape (at least on lions), but it certainly seems to cause the lockup most frequently. I beleive Uros has the patch you are speaking of. Thanks.

Is it a patch to the kernel? If so, which kernel version it will be/is incorporated into?
