next in thread | raw e-mail | index | archive | help
I've got an issue with 8 RELEASE when booting (with / on a USB drive).
It appears that the USB devices are slow to probe. There is a different
latency until the drives are detected, seemingly on every boot
(occasionally, / will come up and not require me to enter the ufs:
line). Sometimes it takes multiple entries of the ufs: line even after
the device gets probed/detected.
This happens on amd64, with a variety of chipsets (nvidia and intel, at
least). It happens with a variety of different flash drives (I've tried
at least 5 at this point, each of a different size/manufacturer/vintage.)
Any help on this matter would be greatly appreciated. I've got a number
of 7.* systems I've got to upgrade to 8 (all with /boot or / on USB
flash due to use of ZFS), and I'm still fairly new to the FreeBSD
experience. Any pointers on how to fix this in 8 RELEASE or whether/how
to upgrade to 8 CURRENT would be appreciated.
Many thanks.
