System hangs using Sony Ericsson gc89 pcmcia card
Last modified: 2007-11-30 17:12:07 EST
Description of problem:
I id an upgrade form fc6 (x86_64) to f7 (x86_64) on my Thinkpad T60 (output of
lspci in attachment) without the gc89 cart inside. After upgrade I've putted in
the card and reboot computer. System was hanging on sysstat. Without the gc89 it
was working fine (I had some problems with ethernet controller, but that's not
important). When I've put in my card after system startup it wasn't hanging
computer (not always) but I've never been able to establish a connection. The
best case was:
1. insert card - kernel detect it and gives it /dev/ttyS0 name
2. #setserial /dev/ttyS0 baud_base 460800 - turning on the cad
3. #pppd call connect-iplus
and after a few seconds system hangs
4. Sometimes system hanged earlier, for example on card insertion - either it's
random or I cant see any reasons why it's not olways the same.
Right know I did a full update via yum and eth0 (sysstat was updated) and it
looks like this:
1. System doesn't hangs on sysstat ... but it hangs on haldaemon
2. Any action performed on /dev/ttyS0 (after putting the card in with working
system) done by setserial or pppd (for example "setserial /dev/ttyS0) causes
system to hang
3. When system is hanging and I'll put out the card after 2 -3 seconds makes
hard reboot (it was like that from the beginning)
4. It still hangs sometimes (randomly?) when I just insert the card
5. There is nothing in any logs - system is working fine and suddenly starts to

Output of lspci
Kernel 2.6.21-1.3228.fc7 didn't change anything... Any ideas?
Kernel 18.104.22.168-41.fc7 didn't change anything either nor the previous ones. I've
installed F7 on different laptop (Asus) witch x86 architecture and the symptoms
ware very similar. Does anyone have these problems?
Is anything written to the system log when the card is inserted?
Is the system really frozen totally? e.g does pressing capslock
turn the light on and off? Does it respond to the sysrq key?
Be sure to enable the key before trying anything
# echo 1 > /proc/sys/kernel/sysrq
alt-sysrq-p should show where it is stuck if it's looping.

Output of /var/log/messages after inserting card
I've created attachment witch output of /var/log/messages. As You can see there
is "usual stuff" and suddenly syslog restarts after I did
System is completely frozen, no capslock, no sysrq, no anyting.
What is in the file /proc/interrupts after inserting the card (but not trying to

As I can see the /proc/interrupts didn't change after inserting the card, but
dmesg shows that the card runs in IRQ 16:
ACPI: PCI Interrupt 0000:16:00.1[A] -> GSI 16 (level, low) -> IRQ 16
0000:16:00.1: ttyS0 at I/O 0xa000 (irq = 16) is a 16550A
Serial doesn't claim its interrupt until first use of the port.
Did the gc89 work in FC6?
Yes it worked fine in FC6. As I mentioned in my first post, the problem started
after upgrade to F7.
I did an additional check to be 100% sure. I've booted from livve cd's and it
looks like this:
Fedora 7 test4 - runs fine
Ubuntu 7.04 - runs fine
Fedora 7 - hangs...
Try adding "pci=nomsi,nommconf" to the kernel parameters in grub.conf.
Also, try blacklisting the ssb driver by adding this line to
I'm afraid that nothing worked - the system still hangs
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest release? The latest Live CD is
and it would be good to know if this resolves this issue for you.
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Hi. Thanks for interest.
To be frank I've gave up and I've bought new modem with HSDPA. But I've checked
today the old one and it works!! ;-) On kernel 22.214.171.124-65.fc7 it still hangs
but on 126.96.36.199-76.fc7 it's working fine. I have no idea what has changed, but I
think I can close this bug ;-)
Great news Piotr, I'm just adjusting the closed resolution to highlight what
fixed it for you.
