Additional P33 flash strangeness

I apologize for breaking the rule of talking about anything but the latest
kernel but I'm stuck no 2.6.10 because that's all that's supported on my
current platform at this time (Freescale Coldfire).
I'm using Intel 256P33B StrataFlash with a jffs2 file system. This flash
supports CFI v1.4 whereas my kernel supports only up to CFI v1.3. I
modified the check in cfi_util.c and cfi_cmdset_0001.c to support
MinorVersion 1.3 and 1.4 (just changed the check, nothing else) and the
sytem boots and runs. However I still get a list of about 50 "Empty flash
at" errors and much more disturbing errors I get at random like:
"0x0077d40c(3) on flash (*c394d2a8). left (00000000), right (00000000),
parent (c394cdf8)"
I get one of these: "Dirent "libnss_nis.so" (hash 0x79acaa59, ino #596"
I suspect an interrupt is causing the text to be corrupted. Not making
much headway on what the problem is. I can read and write the file system.
I've used scp to download a 2.5MB file. The biggest issue is that some
file operations are dead slow. Takes about 2 or 3 minutes to mount the
root file system (8MB). Writing to a small file from vi can take 15 or 20
seconds.
I'm not even sure if this is an MTD thing or a jffs2 thing. Any ideas
would be much appreciated...
