I posted this on the Facebook groups, but I know a lot people avoid Facebook so I thought I'd post it here as well.
I have a ROM 3, 4MB of memory, a Microdrive Turbo IDE Card (DMA is set to ROM3), and a Transwarp (7MHz). I'm running 6.0.4. Normally my system is fine, but now and then when it boots up and starts going through all the hard drive partitions it will get to one it just doesn't like and crash to monitor with errors like this:
00/FF08: 00 00 BRK 00
A=603C X=0A03 Y=0002 S=BFD1 D=BD00 P=00 B=02 K=00 M=00 Q=B6 L=0 m=0 x=0 e=0
It seems to be related somehow to GS/OS displaying partitions. I say this because the crash will happen when the partitions are being displayed on desktop when the OS starts. It seems like the crash always happens on the 5th partition, and it doesn't matter what's on it (even when it's empty). Here's the really odd part though, if I put two disks in my 3.5" drives and boot, the crash won't happen. From that point on the system seems stable even if I remove the disks and reboot. The crash will eventually happen again though.
Here are the things I've already done as troubleshooting:
1. Checked the RAM. All tests are good.
2. Checked the voltages on the power supply. They're all in spec with the only odd one being the -5V showing up as -5.2V.
3. Turned off my Transwarp (well down to 2.8), didn't change anything.
I'm currently using ADTPro to transfer over hard drive images to my partitions (I have 15), so maybe something ADTPro is doing is not working well with my Microdrive? I don't know if using ADTPRO is what's triggering the crashes to start happening again or if it's all just a coincidence.

It is a "GS/OS crash related" as tbe direct page is set to $bd00 (see D=BD00)
Finder uses the Window Manager simulation of GS/OS low level calls that is called to mount devices. A problem with a device would result in a crash. Another crash reason could be a problem with icon data. Another crash reason could be a conflict between drivers and device assignment (but frankly I've never encountered any)
First thing I would do:
- boot a floppy with Copy II Plus or a System 6.0.1 system disk and remove all Finder.root and Desktop files from all the paritions Icons folders (files are hidden IIRC)
- if NG, I would remove one partition after the other and see which one crashes the system,
- if NG, I would deactivate non essential drivers (for instance SCSI ones if you have no scsi drives)

Thanks for the possible explanations. My guess is that it's something to do with the icon files on each partition. I decided to consolidate them all onto the main drive and delete the finder.data files. The problem has gone away (so far) so maybe that was it?
