Brief description: System hangs (freezes) completely. It does not
respond to any keyboard presses, mouse movement or button clicks.
Indeed, it won't even allow turning off the laptop using the power
button (use of emergency shutdown relay is necessary). Needless to
say, the filesystem has to be manually cleaned every time, and even once
or twice a week is too much in my opinion.
The problem occurs sporadically when netscape (4.78-2) tries to fetch a
"complicated" page. It does not occur reproducibly on any given page.
A similar problem occurs so frequently with mozilla
(mozilla-2002032709_trunk-0_rh7) as to render the latter unusable. The
system -- a Dell Inspiron 3500 -- is running Redhat 7.2
(kernel-2.4.9-31), and is connected to the net via an ethernet
PCMCIA talking to an Alcatel 1000 ADSL (which then obviously connects
via ADSL). Presumably this is also a sign of bugs in mozilla, but in
any event whatever mozilla is doing should not trigger this. There are
no messages in /var/log/messages.
