[syslinux] pxelinux 2.04+ hangs after loading kernel

[Josef Siemes]

Hi,

I just tried to boot my token ring devices with 2.05 - to no avail,
it hangs after loading the kernel. I then tried older versions, and found
2.03 booting like a charm, and every 2.04-pre including 2.04 hanging.

Here's the config of the devices:
- Networkstation 2800 with IBM PCI Token Ring card 2
- IBM Thinkpad T21 with IBM PCI Token Ring card 2

Maybe this has to do with the changes regarding blksize. At least
the hang in 2.04-pre1 comes much faster than 2.03 boots the 
kernel. I'll try to get some network dump of the boot, but that's 
not really easy with token-ring ...

pxelinux.cfg:
prompt 1
default 28t
timeout 30
implicit 0

label 28t
        kernel lfs28
        append nfsroot=10.1.1.53:/usr/local/linuxnc/2.8-t/img devfs=mount ip=dhcp

label 28t-check
        kernel lfs28
        append initrd=initrd28 root=/dev/ram0 init=/linuxrc devfs=mount ip=dhcp
