Could you feed these oopeses through ksymoops? 

I'm now running vmware 24h/day with linux and win98 as guest, doing
network transfers between host and guest, and I did not noticed any problems.

It worked fine with 2.4.5-ac24 from wednesday to sunday, and yesterday
I upgraded to 2.4.6-ac2, and it still works. Kernel compiled with
Debian's gcc-3.0-3 or gcc-3.0-4, Asus A7V, KT133, 1GHz Athlon, and
Chaintech 6BTM, 440BX, 300MHz Celeron... I did not tested Linus's kernel
for more than 6 months now, so I cannot tell whether it works with Linus's
2.4.6, or not...

Thanks, meanwhile I found simillar report on VMware newsgroups, so there must be
something really real (it was with example how to reproduce it, so I received
fine oops too).

Following patch fixes oopses, at least for me. Due to some changes in tasklets
and/or in networking there is now very large quantum of skbs in flight from
one part of vmnet (packet written to /dev/vmnet*) through netif_rx to another
(packet received on eth0 interface). This trigerred 'history buffer overflow'
message, which then started cleaning history buffer. And if two CPUs started
cleaning at the same moment, one of them did kfree_skb(NULL) sooner or later...

So only increasing VNET_BRIDGE_HISTORY from 8 to 48 fixes problem, but as
I do not want oopses, rest of this patch just fixes oopses themselves. If
you'll apply patch except VNET_BRIDGE_HISTORY line, it will work, but you'll
get large stream of 'history buffer full' messages when doing TCP transfers
between guest and host. (48 is apparently enough for dual PIII/800, I did 
not tested lower values (48 is next multiple of 8 which ends on 8,
this saved one keystroke and so on...))

For those unfamiliar with patch (I'm sure there are no on linux-kernel,
but there can be some in VMware newsgroups) I put updated vmnet.tar.gz
at ftp://platan.vc.cvut.cz/pub/vmware/vmnet-204-for-2.4.6.tar.gz

Thanks,

Patch fixed the problem. Thanks.

Just happened again. This only happens when there is a lot
of network activity. This time I was downloading an mp3 from

VMWare crashes

[Gary White (Network Administrator)]

I realize this may be a VMWare problem, but I just waited to
bring this to the attention of the developers in case it was related
to the kernel and to also see if anyone else is having the same
problem. VMWare dies under load with all kernel versions up to and
including ac versions after 2.4.6. Kernel version up to and including
2.4.5-ac15 I know all run fine. Somewhere between 2.4.5-ac15 and 2.4.6
is where the problem started. I have backed up to 2.4.5 now and VMWare
is rock solid.

You'll need to pass teh stuff above through kysymoops to see anything
useful.

I havent had problems running vmware and I usually have it running days
