web, so I post this problem.
I think I have post all necessary info. If you need more info, fell free to contact me.
[1.] One line summary of the problem:
Linux reboot when using Deflate with compression set to 8
[2.] Full description of the problem/report:
When we use pppd with deflate compression enabled and to to the min for compressor (8), after a
short use of the session (read of a web page) linux reboot.
I haven't find any message or log about it.
[3.] Keywords (i.e., modules, networking, kernel):
kernel, modules, ppp, deflate
[4.] Kernel version (from /proc/version):
I have try this on two version that I can't upgrade because there are used for other development.
