Re: Applying e1000e patch to the Debian 2.6.26 kernel
Hi,
I was wondering about the status of this patch. Will it be included in
the next Lenny ? Note that we are currently maintaining a patched
version of the Debian kernel on our repository, we are using the patched
version on all our servers for months now, and we have noticed no
regressions. It would be great if the decision to include them was
taken, as it's a pain to have to patch, and compile, each time there's a
security issue that triggers an upgrade.
Thomas
P.S: For the record, I have attached the 2 patches to this message once
more.

e1000e: test for unusable MSI support
Some systems do not like 82571/2 use of 16-bit MSI messages and some
other systems claim to support MSI, but neither really works. Setup a
test MSI handler to detect whether or not MSI is working properly, and
if not, fallback to legacy INTx interrupts.
