[gentoo-user] Firefox 4 hard freeze

[Willie Wong <wwong@math.princeton.edu>]

Hi list, 

I'm running into some weird problem. Firefox was upgraded to version 4
a few days ago. And up until last night I have had no problems with
it. Starting this morning, however, it seems that Firefox would freeze
up whenever I touch the keyboard with the window in focus!

I can open new tabs, go visit links in the history, etc, with no
problems. But any keyboard input (hitting Ctrl-t for new tab, Ctrl-n
for new Window, or trying to enter an address into the address bar)
completely freezes the program. 

Running from command line produced no outputs. 

Running with `strace` gives the following output near the end. I am
not sure what's going on with the read(3, 0x9038118, 4096) thing which
keeps giving Reseource temporarily unavailable: it keeps flashing by
once Firefox has started, seems like firefox keep trying to poll
something, but I have no idea what it is doing. 

But at the very least, even when I just leave the window alone, I knew
firefox was doing something. 

But the minute I hit the keyboard, the rapidly scrolling output of
strace stops, and I had to hit Ctrl-C to terminate the process
(resulting in the last line of the posted trace). 

The running versions of firefox is 4.0-r3, and xulrunner is at 2.0-r1

Any ideas?
