I'll take this bug, if that's okay with you, Tomas. Cheers, Jeff (In reply to comment #1) > I'll take this bug, if that's okay with you, Tomas. > > Cheers, > Jeff OK, thanks, Tomas I've seen a sprinkling of these bugs across RHEL 4 and RHEL 5, and they all seem to involve cciss devices (and multiple different driver versions). I'm inclined to think that this is a firmware issue. If someone is able to reproduce the problem reliably, then we can work with HP to zero in on the problem. Does anyone have such an environment? |
