Subject: More mtd problems: scheduling while atomic
Date: Mon, 6 Dec 2004 14:57:03 +0100 [thread overview]
Message-ID: <20041206135703.GA2899@metro.cx> (raw)
Hi All,
Another problem with the mtd driver it seems. This time i'm looking at
cfi_cmdset_0002.c, and it seems there's more horrible bug stuff in there
(see the dump below).
I'm at this point clueless at what to do with this. It is causing me
trouble however.. Is this a known issue?? Any hints whatsoever??
It's with 2.6.10-rc2-bk17 btw..
Koen
