Ben, fancy writing a boot-time test?
I'd never rely on such a test - what if the cpu checks in 99% of the
cases, but doesn't handle some cases ('rep movd, everything unaligned,

A good point. The test results are inconclusive.
And check the Pentium

Ben's test uses only one CPU.

Upgrading from 2.2.18 and 2.4.0 to 2.4.1-ac15 broke pcmcia.
I have a Dell Inspiron 8000. Trying to use pcmcia with kernel
(yenta_socket) or pcmcia-cs only causes pcmcia card to take irq 11,
which my eth device is on also. This didn't happen with 2.2 or 2.4.0
kernels.
What param would I pass
I was wondering why video drivers are not part of the kernel like every
other piece of hardware. I would think if video drivers were part of the
kernel and had a nice API for X or any other windowing system, would not
only improve performance but would allow competing windowing systems
without

Hello everyone,
I think Alexander Zarochentcev and I have finally figured out
cause for null bytes in small reiserfs files. reiserfs stores
parts of these files packed together in the tree, and the
packed bytes can shift around as the tree is balanced.

I should add that the behaviour of serveraid under 2.4 is somehow

It just a gues, but try disable write back cache.

It is?
Not now it isn't. We just do a msync() + fsync() for msync(MS_SYNC). Which
is admittedly not optimal, but it works.
Ok, munmap() will be fixed by

Is it possible to integrate that into the mmu gather code?

Not even necessary.
The D bit does not have to be coherent. We need to make sure that we flush
