Hi there.

I have a question about a Really Odd Occurrence I've noticed with
2.2.1 on a server I attempted to use it on.

For whatever reason, under 2.2.1 the server stops talking to its
hard drive after about 2 hours 45 minutes. Consistently. We've tried
several things, none to any avail. Note that the machine works just fine
with 2.0.36 distributed with RH 5.2.

The machine in question is a 486 dx4/100 using a UMC8886BM ide
controller. It has ISA and PCI, and I think even a VLB slot (unused). The
hard drive in question is a Western Digital WD34000L (4GB). From 2.0.36:

hda: WDC AC34000L, 3815MB w/256kB Cache, CHS=7752/16/63
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14

The most recent configuration has IDE DMA disabled, and
ide0=umc8672. Prior to that, we booted w/o ide dma in the kernel, and w/o
using the umc8672 stuff (both of these had support for most of the chipset
workarounds). Prior to those, the 2.2 kernels we built had support for
ide dma, but hdparm indicated that the dma was not being used.

The /proc/pci is attached, as is /proc/cpuinfo.

The biggest problem is that this is a production machine, and due
to people continually logged in I can't take it down often. Not exactly
ideal for testing. Since 2.0.36 works, that's what we're sticking to, but
NFS is used on it, so I'd like to move it to 2.2. But with it locking up
after approximately 10,000 seconds (the kernel's not thinking in decimal
now, is it?) _every_ time, I can't exactly leave it on that.

Any ideas? Suggestions? If more info from the 2.2 side of things
is needed, I can probably boot it to that at some point, pull the
information, and boot back to 2.0... but I'd like to keep that to a
minimum.

Thank you everyone. I really appreciate all your hard work
getting 2.2 out there.
