Heh, nice! :-)
I've been so dug up in debugging the USB cache issues I didn't bother to look
around the list for previous efforts. So obviously, apply Eric's patch! :-)
Hi guys,
It looks like I missed this bit though:
diff --git a/fs/fat/fat.c b/fs/fat/fat.c
index 1f95eb4..d709e59 100644
--- a/fs/fat/fat.c
+++ b/fs/fat/fat.c
@@ -709,7 +711,7 @@ read_bootsectandvi (boot_sector *bs, volume_info *volinfo,
int *fatsize)
return -1;
}
- block = malloc(cur_dev->blksz);
+ block = memalign(ARCH_DMA_MINALIGN, cur_dev->blksz);
if (block == NULL) {
debug("Error: allocating block\n");
return -1;
Perhaps I got lucky in my testing!
Regards,
Eric
