[OpenAFS-devel] OpenAFS on RH Linux 2.2.19-6.2.7enterprise kernel (again)

[Alf Wachsmann]

Hi,

I now get OpenAFS-snap-2001-08-28 compiled, loaded and started on
RedHat's Linux kernel 2.2.19-6.2.7enterprise.

But as soon as I "stat" a file in AFS I get an OOPS:

Unable to handle kernel NULL pointer dereference at virtual address 00000061
current->tss.cr3 = 10d1f000, %%cr3 = 10d1f000

"strace" also shows that the last thing happening is an "lstat64()".

Any ideas what's wrong?

Does it matter that in src/afs/LINUX/osi_vnodeops.c the
"struct inode_operations afs_iops" has two fewer intries than my
system's <linux/fs.h>?


Thanks,
          Alf.
