Re: kernel 2.6.15, PPP, keyboard failure and freezing
Hi again.
By having a look at syslog after a freeze I discovered that the kernel was
oopsing:
Jan 28 09:05:16 phi kernel: skb_over_panic: text:ffffffff8876790c len:1 put:1
head:ffff810022437000 data:ffff810122437000 tail:ffff810122437001
end:ffff810022437600 dev:<NULL>
Jan 28 09:05:16 phi kernel: ----------- [cut here ] --------- [please bite
here ] ---------
Jan 28 09:05:16 phi kernel: Kernel BUG at net/core/skbuff.c:94
Jan 28 09:05:16 phi kernel: invalid operand: 0000 [1] SMP
Jan 28 09:05:16 phi kernel: CPU 1
[...etc...]
On the suggestion of Christoph Fassbach I gave wvdial a whirl to see if it
behaved similarly. It seemed to work flawlessly, until a couple of minutes
after connecting when the machine froze, much like it had done when using
KPPP. wvdail seems to give a delayed reaction. A similar result appears in
syslog.
A bit of googling with the syslog stuff and I found that this problem is known
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=347711,
http://bugzilla.kernel.org/show_bug.cgi?id=5857), has been discussed
(http://lkml.org/lkml/2006/1/15/113), and a patch exists
(http://bugzilla.kernel.org/attachment.cgi?id=7086&action=view).
I'll add a note to the Debian bug shortly.
Peace,
Brendon
