Hi, all:
My PC have 128M RAM, but in /proc/meminfo, it display 122424K, not

My program need to a 32M buffer, so I add "append="mem=96M"" to lilo.conf,
then the PC only know 96M mem, I can use the rest 32M. Following is a
simple example:

Your patch cannot be correct, it is impossible for CONFIG_NETLINK_DEV

I hit the same bug() an hour ago.
It was preceeded by a complete system lock up (not even sysrq worked)

The lockup happened whilst I was diffing two kernel trees.

Thanks for your feedback. We are looking at this now. Hopefully we will be
able to give you a response on Monday. If we don't then it's because most
of us are on holiday next week.

mxcsr is per-process thing and it's saved and restored with the fpu and it

you're right, it would break it, the driver should really somehow increase the

We have some problem with the quota with only SOME users.
Is there any new version of quota which fix this kind of

2.4.0-test9 (and maybe test8) had some significant changes that broke
several USB drivers, including cpia USB.

I want to make a Bootable RAID.
can I make a partition on the disk which I want to
