Re: [PLUG] Kernel upgrade woes

[Greg Lopp <lopp@pobox.com>]

Took a look while in "recovery mode" (aka single user mode) and found 
the udev was not installed. 

Booted into an old 2.4.27 kernel and didn't have any mount problems.  
Then rebooted into the 2.6.10 kernel without mount problems.  I have 
repeated that pattern: 2.4.27 to 2.6.10 and it's OK. 2.6.10 to 2.6.10 
and nothing works.  What is this /etc/blkid.tab anyway?


On a different note, it appears that I can no longer build a kernel.  
After several warnings about "pointer tagets" " differing in 
sighnedness", I fail in arch/i386/kernel/process.c when the assembler 
errors out, informing me that "suffix or operands invalid for 'mov'"   I 
thought that I'd removed all those cross compiler tools....could a 
config file have been missed somewhere?
