Hi all
I've been buggering the list with this ridiculous problem for quite some
time now:-) I understand, it is too risky to apply an untested patch to
mainline, but could we either
1) get it into -mm
or
2) try to find some beta-testers by applying something like the below:
Thanks

O... Ok, before you discover it yourself - the fault is mine, to be
more precise, my patch, that somehow got applied... The long interesting
discussion

That's a highmem bug. IIRC, Guennadi said that highmem does not
(or may not) work correctly in this driver, so I should have
asked you to test with HIGHMEM disabled so that the other bug
can be addressed.
I have now tried 2.6.12{,.1,.2} and only 2.6.12.2 breaks

Hi Pierre,
Does this happen on every boot?
Please send your .config file (or put it on craffe.se).

Does this happen with othe kernel versions?
Not that I've found. I could try compiling the currently running kernel
(2.6.11.7) without highmem if you'd like.
I'm having some problems with your mailserver Randy. I'll cc the mailing
list hoping you'll see this there.
I get:
550-Verification failed for [EMAIL PROTECTED]
550-unrouteable mail domain drzeus.cx
550 Sender verify failed
As far as i know my MX records are completely correct.

Quite right. The limit is slightly before 1 GB, not exactly at it. My bad.

3c59x.c has CONFIG_NET_POLL_CONTROLLER code in it.
I would expect it to work since it's a fairly common NIC, but I
can't vouch for it.
Did you enable CONFIG_NETPOLL in your kernel .config?
Yup. It's enabled. NETPOLL_RX is not enabled though. Is that needed?

Pierre,
Can you capture the complete panic message using serial console or
netconsole? or at least use a smaller font on the console so that
we can see the entire panic message, as some critical parts of it
have scrolled off the top of the screen.
