Hi all,

I don't know if anyone else has reported this thing, but after changing
my /etc/fstab file to mount the dos partitions as vfat systems, I get
sometimes the error listed below when booting, but the strange thing is
that this error only occures after 2 or 3 reboots....mainly it happens
when I start linux the first time after switching from DOS. My computer
Setup is:

Linux Kernel V2.1.26 with no SCSI/ISDN support running on Pentium 100Mhz,
32MB Ram (Soyo 82430 FX/P54C PCI Motherboard), 100MB Swap Partition,
Spea V7 Mirage P-64 Videocard, Pro Audio Spectrum Pro 16 Soundcard
(enabled sound support in Kernel), Novell NE2000 Ethernet card (ISA),
Both internal IDE adapters are used with 3 HD's (see bootlog below for data)
and one quadra speed CD-Rom.

This error will be printed when booting the kernel via Loadlin V1.6a:

Here the fs systems are mounted, and randomly on one of the 3 vfat
filesystems the following error occures:

Feb 27 17:48:41 punishment kernel: pppd forgot to specify route netmask.

Here also the network interface reports errors, but if the kernel boots
without the error above, the network will initialize without problems ?!

I have also all required programs with the correct versionnumbers installed
as listed in the Changes.txt file.

Another problem I have is when compiling the kernel GCC (2.7.2.1) stops after
compiling about 10 minutes with a signal error (15 or 11) and I have to
reboot to continue successfully the compiling progress. Without rebooting,
GCC reports random errors inside the kernel sources, but after the reboot
everything is fine ?! Very strange, I think...

If more infos required, I will post them on demand, but this is my *first*
bugreport here ;)
