Re: Raid1 stalls during hotplug and Promise SATA TX4

[David Greaves <david@dgreaves.com>]

not sure about this but it looks like the problem is occuring at a lower 
  level than md.

I'd take it over to ide-linux and/or hotplug.

ide-linux is at linux-ide@vger.kernel.org
I don't know about hotplug

It would help to tell them what kernel you're running too <grin>

so /dev/sdc is toast, not /dev/sdb

oops, so is /dev/sdb
