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 boot. Version-Release number of selected component (if applicable): kernel 2.6.21-1.3194.fc7 sysstat 7.0.4-2.fc7 hal 0.5.9-8.fc7
Created attachment 156675 [details] Output of lspci
Kernel 2.6.21-1.3228.fc7 didn't change anything... Any ideas?
Kernel 2.6.22.1-41.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? http://en.wikipedia.org/wiki/Magic_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.
Created attachment 160506 [details] 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 #setserial /dev/ttyS0 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 use it?)

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 /etc/modprobe.d/blacklist: blacklist ssb
I'm afraid that nothing worked - the system still hangs
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage 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 available from: http://fedoraproject.org/wiki/Distribution/Download 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. Cheers Chris
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 2.6.22.4-65.fc7 it still hangs but on 2.6.22.5-76.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. Cheers Chris
