I tried the 2.6.15.1-2.6.15.4 and 2.6.16-rc5 kernels, and all of them gave
almost the same error like:
Unable to handle kernel paging request for data at address ...
And if I don't use -b option of systemtap, it seemed that it could run for a
long time without kernel panic.
And I also noticed that the kernel reported the I/O error even when I wasn't
running systemtap and only did some simple writing operations:
end_request: I/O error, dev sda, sector 17445
end_request: I/O error, dev sda, sector 17447
end_request: I/O error, dev sda, sector 17449
Aborting journal on device sda2.
ext3_abort called.
EXT3-fs error (device sda2): ext3_journal_start_sb: Detected aborted journal
Remounting filesystem read-only
The same version of systemtap could run very well with 2.6.9-30EL, so it is a
bug of the mainline kernel.
