Patching 8390.c won't fix this for me. The only thing on IRQ19 when I saw

Gentleman, this (the patch to 8390.c) seems to fix the problem.

Ingo, is that possible?
The current fix is "disable_irq_nosync() and enable_irq() cause
from "Linux-2.4.x patch submission policy":
Another way of putting it: if you have a patch, ask yourself what
would happen if it got left off the next
RedHat/SuSE/Debian/Turbo/whatever distribution CD. Would it really
be a big problem? If not, then I'd rather spend the time _really_

great. Back when i had the same problem, flood pinging another host (on

ping -f -s 10 otherhost
this produced an IOAPIC-hang within seconds.

Hi,
The starfire driver in 2.4.0 (and 2.4.0-ac8) forgets to release its MMIO
region when the module is unloaded, which makes it impossible to load it a
second time. The attached patch fixed this problem; I tested it here on a
2-port card.
Please apply.
Thanks,
Ion

Hmm. I would think that increasing the logical page size in the kernel
would be the trivial way to handle virtual aliases. (i.e.) with a large
enough page size you can't actually have a virtual alias.
There are types of caches out there that no matter how large the

Hi guys,
This code for generic_file_write calls vmtruncate without i_sem held. Is

Erm... generic_file_write() grabs i_sem upon entry and drops it on exit.
