Hello,
I think that I have found a bug, and as I haven't found any information about this problem on the 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.
[1st computer] Linux version 2.2.5-22 (root@porky.devel.redhat.com) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 Wed Jun 2 09:17:03 EDT 1999

[5.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt)
I haven't find Oops message
[6.] A small shell script or example program which triggers the problem (if possible)
Set pppd options : deflate 8,15
connect and use it.
