Hello,
Hmm, I can't understand this. I want to buy a new system including

"right" choice. However I'm using *only* Linux (well, sometimes BSDs,

Hi,
I don't know if this is a bug, but on kernel src code, `-' and `,' is
substituted to `_' in scripts/Makefile.lib but, in latest

Attached is the patch for this problem against module-init-tools.

I'm new at this so I'm learning my way through it and I'd appreciate any
guidance. My system freezes solid intermittently for no apparent
reason. The serial console shows a kernal panic caused by a machine
check exception. mcelog decodes the MCE as follows:
CPU 0 4 northbridge TSC f03d1e587b

Rename to nr_pages
This panic would only occur in saving panic information to the
system log in another panic, and only when sending the panic
information to a remote management controller, so it's not a huge
deal, but needs to be fixed. Hopefully pasting the message inline
will work ok (testing showed it to be fin

I disagree with your definition of a system call

Hi.
There is a problem in the accounting subsystem in the kernel can not
correctly handle files larger than 2GB. The output file containing
the process accounting data can grow very large if the system is large
enough and active enough. If the 2GB limit is reached, then the system
simply stops
