kernel crashes while trying to copy 700mb zip file from FAT32 partition to /boot/home

Can't do much testing with kernel constantly crashing here, so would appreciate any help with this.

Similar looking tickets: #12408 and #12518.

Copied the same zip file to bfs using bfs_shell form macOS and tried to unzip it in Haiku (to exclude fat32 driver as a possible source of the problem) and got the same KDL after a few seconds of unzipping.

Unfortunately, even after entering it using /bin/kernel_debugger keyboard doesn't work. But I'm able to build Haiku to this partition and take pics if you want me to try any patches.

Still here in hrev53104.

#12408 is probably related here. bonefish noted in that one that the page structure was overwritten with bogus data, that's probably the real cause.

#15912 may actually be related here, if the file_cache was overwriting pages "randomly". See if you can still reproduce this after the fix to that. The bootloader changes may also be relevant, so see if that helps.

I couldn't reproduce it after using Haiku on this MacBook Pro for an hour. However, I didn't try to copy from fat32 partition as I don't have it currently. Hopefully fixed.

Well, the file_cache changes and the bootloader changes are the most likely, so it would be good to test copying from a FAT partition.
