Hi -
If I'm not wrong , you should provide rootfs as an argument -
./linux ubda=/path/to/rootfs
If that didn't work,please post the exact compilation steps and exact error
messages.

Hello everyone!
I have a problem with debugging a kernel module with UML. The module works OK
on a regular machine, but when i try to debug it whit UML it seg faults with
the following trace:
Program received signal SIGSEGV, Segmentation fault.

Hi all
So far I have found my issue of memory corruption in my initialization
routine.
So far I can do mapping of pages to a user space program and unmapping them
correctly inside UML. So let's me explain what we do in our current box.
1. The driver allocates a big compound page to server as a po

Hi
One last important detail. The module works creating the mmap driver
operation. The driver uses vm_insert_page and getting the pages with
__get_free_pages. Would that be the problem???
thanks

Hi All
I am having problems with LKM compiled for UML. I am porting some drivers

I am getting the famous segmentation fault problem (with
dig, host, bind, etc). However, I have no /lib/tls under
either the guest or the host systems. (I have deleted every

I've just done it and it's already working.

Well I'm no kernel expert, but it so
Hi , my fedora core 2 guest
have this problem:
host -a somedomain.comipv6: version magic
'2.6.9-1.6_FC2 686 REGPARM 4KSTACKS gcc-3.3' should be '2.6.9-bb4
gcc-3.3'Segmentation fault
I use kernel 2.6.9 bb4 on guest and 2.6.10 skas v7
on the Host.
Have you some ideas?
Thanks
