I've been using VMWare 4 with 4K stacks running linux, netbsd and > win2k on a system with a 30day uptime, i'm using ext3 on 2.6.7-rc3-mm2. Quite true, and a good point. However, this is one case that can be reproduced - not systematically, but with certainty - and which displays a clear difference between 4k and 8k stacks. Enabling noisy debugs and tagging on a serial console might catch something.=20 My co-worker uses a FC2 stock kernel and I remember someone from RH (Ingo Molnar?) saying that those are currently built with 4k stacks. He has had no such troubles, but then, he isn't using XFS. I'm merely providing this as an additional info for those who assume that VMWare knows what they are doing and wish to start debugging the combination sooner rather than later. (Even if 'later' proves to eliminate some dead-end test-case scenarios.) Nathan Scott explicitly requested for information on troublesome setups, so one could say I'm humouring him and granting a wish, of a sort :) --=20 Mika Bostr=F6m +358-40-525-7347 \-/ "World peace will be achieved Bostik@iki.fi www.iki.fi/bostik X when the last man has killed Security freak, and proud of it. /-\ the second-to-last." -anon? --4Ckj6UjgE2iN1+kY Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFBCSdxv829VwOfGI4RAg4cAKCT/tpYaandEoZRJw0hxEpYkw4y9wCgoh1i O0SmrNniDqnG9Z33Xm7hqEY= =BVxy -----END PGP SIGNATURE----- --4Ckj6UjgE2iN1+kY--
