[Bug 652206] [NEW] Regression with RaLink RT2860

[Draeath]

Public bug reported:

Binary package hint: linux-image-2.6.32-25-generic

My netbook (EeePC 1000) can no longer reliably connect via WiFi when
running the kernel included with linux-image-2.6.32-25-generic. The link
will come up for a few seconds to a minute, and will drop and attempt to
reconnect. Reconnection, if it happens at all, takes a long time. The
cycle repeats endlessly. I do not see any unusual activity in the system
logs.

linux-image-2.6.32-24-generic does not exhibit this problem.
