Description Red Hat Bugzilla 2000-04-17 13:52:46 UTC
Under heavy network load my laptop (thinkpad 600x) with a Xircom realport
PCMCIA card will appear to lock up. The machine stops responding to
keyboard and mouse. However, the machine is still visable on the network,
tested using tcpdump. Physically ejecting the card and re-inserting causes
the machine to resume functioning immediately even processing keystrokes
pressed during the delays.

Comment 1 Red Hat Bugzilla 2000-04-17 14:43:59 UTC
Hmm, doing 'scp <big pile of files> /dev/null' seems to work
OK here.

Is your serial port working?

Comment 2 Red Hat Bugzilla 2000-04-22 05:28:59 UTC
This sounds like an interrupt loop, like the xircom driver is unable to satisfy
some kind of interrupt on the card and is looping forever in the interrupt.
This will typically allow other interrupts to be received but not for higher
level processing to occur.  Once you eject the card, then the interrupt source
is gone and normal processing resumes.  I'm unable to reproduce the issue
because all of my Xircom ethernet cards are Cardbus, while your's is pcmcia
unless you just left the little Cardbus detail off ;-)

Does Pinstripe 6.9.5 fix this with the pcmcia update
