discover/ipmi: Increase IPMI timeout to a reasonable value
We've seen some IPMI timeouts during testing - meaning that an IPMI bootdev setting will be ignored. This can result in a machine booting from an incorrect boot device, or missing a 'safe mode' indication, or incorrectly proceeding past petitboot. The firmware & kernel has its own timeout & retry mechanism, so we already have a little error-recovery there; the timeout in petitboot is to prevent an indefinite block if the kernel interface isn't behaving correctly. So, this change bumps the timeout to a value that suits BMCs we've seen in the field (specifying a 2 second timeout, with one retry). Signed-off-by: Jeremy Kerr <>
