Hard lockups solved

Hi,

My lockup problems started increasing in frequency, and it became obvious that they were independent of the kernel I booted. The shoe dropped, nic was failing. It's salvage now.

The bizarre shift errors on ftp are gone, so the data I sent is irrelevant to the kernel.

The soft hangs I was getting were real, though perhaps encouraged by nic failure. Your net/ipv4/tcp.c patch from the NE2000 thread cured them even before I found the hardware fault. Has that patch gone to the queue? I recommend it.

Thanks,
Tom

The bugs I was "fixing" there were due to problems in wait queue exclusivity nesting. We instead fixed wait queue exclusivity nesting so it actually worked in test11-pre3, can you see if by itself that kernel does not show your problems too?

Thanks.

Done. Yes, it's fixed in vanilla test11-pre3, to go by limited testing. ftp, 15 Meg in 4 files -- no deathlike sleep, md5sums agree. That load would have certainly triggered the problem before. On to pre5.

Thanks again,
Tom
