Hi,
since I upgraded from 4.1-STABLE to 4.2-STABLE, my laptop (Extensa 367T)
occasionally locks up hard.
One can force a freeze by suspending (apm -Z) the laptop twice. The first time
it works OK, the second time it locks up.
I played around a bit and found that applying the following patch to
ata-all.c "solves" the problem.
Can anyone tell me, if it is safe to disable the ata_reinit routine?
thanks in advance,
Johannes Hofmann
