Subject: [uml-devel] UML 2.6.10-rc2-mm3 + incremental crashes
Date: Thu, 25 Nov 2004 19:21:01 +0100 [thread overview]
Message-ID: <41A6228D.4050908@fujitsu-siemens.com> (raw)
Have started to test with the new 2.6.10-rc2-mm3 + incrementals tree.
First, it didn't compile, because there are inconsistent definitions
for __pgd_alloc in include/linux/mm.h and arch/um/kernel/mem.c.
I added "fastcall" in arch/um/kernel/mem.c, then the build succeeded.
But now the kernel crashes on startup. Please ignore the error messages
regarding ext3.ko. For the "first shot" I didn't update the initrd.
But the kernel should handle the fs in ext2-mode anyway.
