Bug#479709: maybe solved upstream

[Joergen Bergmann <joergen_bergmann@gmx.net>]

Hi,

for my understanding this bug should have been fixed upstream with 
kernel 2.6.26.6 from kernel.org. So I'm looking forward for the next 
Debian kernel including this patch.

Changelog:

commit 459872ffa5ac2357472118b6a875758a2b11139e

    rtc: fix deadlock

    commit 38c052f8cff1bd323ccfa968136a9556652ee420 upstream

    if get_rtc_time() is _ever_ called with IRQs off, we deadlock badly
    in it, waiting for jiffies to increment.

    So make the code more robust by doing an explicit mdelay(20).

    This solves a very hard to reproduce/debug hard lockup reported
    by Mikael Pettersson.
