Hey Samuel,
Thanks.
Now i am also doing upgrades, and compilations and random things now daily
wanting to see if i can get it to show those issues.
I have deployed the latest ext2fs (so with mmap patch, and also the other
recovery_needed patch that are both in the repo).
This is what i do.
I run it with
qemu-system-x86_64 \
-m 512 -smp 4 -cpu host
-enable-kvm -machine pc \
-drive
file=/home/loshmi/Projects/hurd/debian-hurd-i386-20260314.img,if=ide,index=0,format=raw,cache=writethrough
\
-device ahci,id=ahci1 \
-drive
id=compil,if=none,format=raw,file=/home/loshmi/Projects/hurd/compil.img,cache=writeback
\
-device
ide-hd,drive=compil,bus=ahci1.0 \
-netdev user,id=net0,net=
192.168.76.0/24,dhcpstart=192.168.76.5,hostfwd=tcp:127.0.0.1:2222-:22 \
-device e1000,netdev=net0 \
-display none -no-reboot
-serial file:hurd_debug.log
I give it only 512mb of ram hoping it would stress test it a bit.
Both the root image ext2 is journaled, and the compil.img has a journaled
ext2 in it.
I am doing upgrades daily (two days now).
I am also recompiling hurd and gnumach.
Today I additionally did: (inside hurd)
$ sudo settrans -a /mnt/stress /hurd/ext2fs.static /dev/sd0
ext2fs: journaling enabled on /dev/sd0

So far nothing. Either i untar, or compile, or upgrade...everything just
works without lockup or corruption for now.
Let me know if you think i should change something to more reflect what you
have, i really want to see why it locks up (if it still does that).
I will continue to do this daily, hoping to catch it.
Thanks
Milos
