I got an oops while copying from an ro ntfs to a fresh xfs filesystem.
The cp process froze and was unkillable, some other processes also froze
(even though / was ext3).
After rebooting, recreating the xfs and starting the same copy process
again, another oops occured about 2G earlier than in the previous
copying. This time, nothing froze.
Kernel version: 2.6.21-rc6 #2 SMP PREEMPT i686 (self-compiled with
debian-lenny .config)
a "zgrep 4KSTACKS /proc/config.gz" shows nothing.
First oops:
BUG: unable to handle kernel paging request at virtual address 0000a702
printing eip:
c018559f
*pde = 00000000
