[2.6.25.18-1] kernel oops/warning

[Pawel Golaszewski]

Pojawia się u mnie oops za każdym razem gdy jest robiony hotadd lub 
hotremove (raczej to pierwsze) dysku twardego SCSI. Nie powoduje to 
żadnych utrudnień, ale jest "ciut" niepokojące

Ktoś może to potwierdzić?


Prawdopodobnie to jest rozwiązanie:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=cc74d96f47b0d916840f92092595e3be9731e047
Nie znam tego podsystemu, więc prosiłbym kogoś z ostatnio-grzebiących w 
kernelu o spojrzenie.
