Pri prechodu na 2.2.x ctete soubor /usr/src/linux/Documentation/Changes 
a opravdu upgradujte dle doporuceni! Uzivatele RH by meli upgradovat z 
nejakeho mirroru adresare ftp://updates.redhat.com/5.2/kernel-
2.2/i386/ [jinymi slovy: RH 5.2 _neni_ 2.2.x ready ve sve panenske 
podobe].

Specialni problemy pusobi PPP, kde potrebujete opravdu posledni verzi!

Prikladam take mail z linux-kernel, ktery by mohl pomoct.

Subject:        Resolved: Poor PPP performance in 2.2.x

This is an update to my email from 2/3 to this list.  The original email
with a description of the problem follows this message.

The problem briefly was that I was getting "stalls" or something over
ppp with the 2.2.x kernels.  PPP would stop responding, and an RX error
would appear in "ifconfig ppp0", every few seconds.  Also, a strange
bunch of hex numbers appeared in /var/log/syslog.

The hard disk DMA and IRQ masking suggestions offered no help at all.

I determined that the problem was caused by the bsd_comp module!  I
turned it off in /etc/conf.modules and the problem vanished.  It looks
like there may be something wrong with this module.  I intend to go
back through the kernels until I can find what in that module changed
in order to figure this all out.

Why were so few people seeing the problem?  Perhaps my ISP
(Concentric.net) uses this compression module and many others don't. 
Perhaps many others have disabled this module.  Perhaps it's something
about the system yet...

Anyway, at least PPP is working now!

Stephen
