insert a pcmcia card: BUG: soft lockup detected on CPU#0!

which version of ubuntu are you using?

I am using 6.06 LTS. It is the default(gnome) desktop.

sorry it took me so long, I somehow missed your reply.

I know this one. I had a HP pavillion 4400ze that did this to me. I
eventually figured out that by removing executable permission from
pcmciautils it corrected the problem.

This bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this bug report.
Appears to have been solved with permission change.

The bug is alive and kicking as of 2008-03-03 with 2.6.24-14-386.

When pcmcia card is inserted, dmesg shows:

last line comes after I pull the card (PCMCIA USB 2.0 card) out.

In terms of workaround, I would appreciate if someone finds a good solution (disabling pcmciautils seems to invite breakage because it runs as a service in several runlevels)

emk2203,
Does the work around by clearzen (above) also fix this for you?
Is this occurring for you on "hp pavilion ze4400" as for original reporter?

Gareth,

thanks for asking, no, the work around didn't work for me. I am working
with a Dell Latitude C840. Instead of removing the executable bit from
pcmciautils, I did

update-rc.d - f pcmciautils remove
invoke-rc.d pcmciautils stop

in a root shell and inserted the card (UH-420 from Ultron, PCMCIA USB
2.0 adapter).

Same problem.

After this, activated pcmciautils again with

update-rc.d pcmciautils defaults

since the "fix" obviously wasn't one.

Following the original tip to the letter:

chmod -x pcmciautils
<reboot>
<card insert>

yielded the same lockup result as ever. Other PCMCIA cards tried (SCSI,
SD memory card adapter) work fine.

By the way: the problematic card runs fine under Linux in a Sidux
(Debian Sid) environment on a Dell Inspiron 9300. But it refuses to run
under Sidux live system 2008-01 with the Latitude C840. It runs under
Windows XP on the Latitude C840.

Erik,
thanks for the reply.
The issue you are experiencing is clearly quite different to the bug reported here by "clearzen".
Different CPU, chipsets and graphics.
Your issue seems to be a specific problem between the interfacing of the Ultron UH-420 and probably your C840 chipset & BIOS. Difficult to say for sure at this point. The Ultron UH-420 seems well supported on different hardware as you point out.

I have searched Launchpad for a similar bug but I am unable to find a similar report.
You need to report your issue as a separate new bug in Launchpad. It can't be dealt with here.

When you do please attached the following to your newly created bug:
sudo dmidecode > dmidecode.txt
lspci -vvnn > lspci-vvnn.txt
and the debug info you reported above. Also report operational issues that may be helpful such: Does it boot & work OK with card already inserted (ie. is issue only card insertion?)??
Thanks.
