[ltp] Input devices seem to freeze or hang periodically

Wed, 7 Nov 2001 09:53:07 +1300

My system configuration is similar and one of the (many) fixes I ended up
with were the Turbo Adapter and Memory Leak patches from
http://oss.software.ibm.com/developer/opensource/linux/patches/tr.php

The memory leak one was the one that gave me the same symptoms as you
(variable hang periods etc.). Finally detected by matching # of emails
received in given period...

Hello,

I have a 600x and I seem to have a problem(s) that is similar but not
exactly like anyone else's on the list.

At times my thinkpad seems to "freeze."  Freeze in this case means the
keyboard _and_ mouse seem to be locked (it is always both).  I can't type,
ctr-alt-backspace the server or ctr-alt-del the machine.  I can fn-F4 to
suspend, but when I resume the machine doesn't respond to my keystrokes for
the password (I have a power on password).  The strange thing is I can
usually physically remove my PCMCIA card and everything will come back
alive.  If the password prompt is up, I can then type in my pw and resume.
Keystrokes that I pressed will even be buffered and printed as soon as the
PCMCIA card is ejected.

Occasionally, my system also hard hangs.  Can't ping, can't suspend, can't
do anything but power down.  Related to above?

Here is what I know:

- PCMCIA card is an IBM Token-Ring Auto 16/4 Credit Card Adapter
-  OS is RH 7.1 SBE.  Hangs with kernels: 2.4.3-6, 2.4.13, 2.4.14-pre8
-  Happens in X or with no X-server running
-  Mean time to failure can be hours (normally 10-15 min), but I don't
recall ever hanging or freezing with PCMCIA card _not_ installed
-  APM compiled in or out makes no difference
-  System will freeze or hang while just idling
-  System seems to freeze more often just as I click in a VT window to type
(could be coincidental)
-  Upgraded to most recent bios

Any help?
