I can confirm the bug which loses updates to the inn active file when
it's unmapped is present again in 2.4.0-test12.
I put "cp active active.ok" in the rc file before shutting down the
daemon and at the next boot the files are different, every time.

I run 2.2.19pre3 on a BP6. No OC, no vmware. just the kernel wilt
lm-sensors stuff patched in.
I found that the kernel was somewhat sluggish now and then, and
this morning, this popped up in the logs :

Yes, I overlooked start_tx.
Hmm. start_tx also assumes that the cpu commits writes in order, I'm
sure the driver is unreliable on RISC cpus.
Perhaps the driver should use pci_alloc_consistent and pci_map_single?

It is also still in 2.4.0-test13-pre4 in case someone thought they had
fixed it.

Hello to everybody
This is a kernel patch against linux-2.4.0-test12. It includes only a few
small code changes to make my Compiler (GCC 2.97) not complaining so much.

OK. I went back to 2.2.18 (released) and things
work better.
Since it appears the debug flags don't work in the
8139too module, how can I turn on some debug flags
in the 2.4.0-test13-pre4 driver so I can see where
this thing is hanging?

I've not yet started active searching. However:
Hello Dag,
I discovered that my notebook supported FIR, but I didn't know the chip (and it
was not documented). So I disassembled it completely and found an SMC FDC37N769
inside. It's now correctly detected with the following trivial patch against
kernel 2.2.18 (the same entry should be added to
G !
For Christmas, I'd like to get a new mailer which doesn't eat my patches :-)
here it is again, after cut'n'paste. Please apply by hand or "patch -l".
Cheers,
Willy

No. PG_dirty is used for all memory mapped pages - be they anonymous or

Somewhere between test12 and test13pre4ac2 (sheesh the version

Playing a CSS disc (using xine) causes a complete system hang (machine

still OK.
This is on a

Hi,
I'm trying to debug a weird problem with Xine - its screwing up its use
of shared memory for regions I haven't sussed yet. One odd consequence is
that it has apparently successfully managed to allocate a 0 byte chunk of
shared memory; shmat is then called with shmaddr=0 and shmflg=0; the

It seems that just about everything that uses devfs
contains some logic that attempts to construct an unused
device name with something like:
static devnum = 0;
sprintf (name, "lp%d", devnum++);
devfs_register_device(..., name,...);
