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 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
