Description Wolfgang 2006-01-11 13:04:02 UTC
Most recent kernel where this bug did not occur: 2.6.9 (did not test any later) 
Distribution: 64bit Debian 
Hardware Environment: AMD64, PS/2 keyboard, 3COM US Robotics modem 
Software Environment: dist-upgrade on 2006-01-10 
Problem Description: First: I am not really familiar with kernel bug reporting. 
So if you have questions, ask me at wol (at) kulmbach (dot) net 
 
I did a dist-upgrade and a kernel-update from 2.6.9 to 2.6.15. Afterwards: When 
I do a pon, a bug report (attached below) is filed to the logs. The behaviour I 
observe is: I seem to get no connection, although it seems to login at my 
provider. AND: My keyboard stops working while it dials. So after the first 
pon, I have no keyboard until rebooting. 
 
After several seconds, the modem shuts up.

Another ppp failure in 2.6.15.  This one led to a panic.

Comment on attachment 7048 [details]
/var/log/messages helpful portion - bug does not disable keyboard but network definitely yes

bug appeared twice today while surfing the web via bluetooth and gprs,
Comment 4 Flavio 2006-01-17 12:24:19 UTC
bug causes oops (my arch is AMD64) for rfcomm and bluetooth gprs connection
remains stuck
Comment 5 Herbert Xu 2006-01-21 02:08:24 UTC
This could be a hardware problem or a compiler bug.  The data/tail pointers are
off by about 0x100000000.

Is this a vanilla kernel?
Comment 6 Daniel Drake 2006-01-21 03:13:18 UTC
We have the same bug reported downstream:
http://bugs.gentoo.org/119467

I have asked him to reproduce it on vanilla 2.6.16-rc1 and will get back to you
Comment 7 Chuck Ebbert 2006-01-21 10:06:05 UTC
Should be fixed by:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8243126c5e29030bf1a3fb75187a513966dcba62

I can't tell if it's queued for -stable or not -- it should be but
the tree hasn't been updated for a while:

http://www.kernel.org/git/?p=linux/kernel/git/chrisw/stable-queue.git;a=summary

Would somebody please close this bug?
