#18621 closed bug (fixed)
git operations hang the system

Description
I created a new VM with haiku beta4 (x64) I'm using it to develop. After a while, doing any git operation (on haikuports repo) results in git hanging. If I try to kill the git process, the whole system sort of hangs (but I'm still able to move windows around).
I tried upgrading to master but the problem persists.
I'm using qemu/kvm on Ubuntu 22.04 with 2 vcpu and 4GB ram. I've tried different NIC drivers (e1000, virtio, rtl8169) but without changes.
It's hard to give more info since I cannot open anything while the system is hanged.

And if the syslog does not contain the relevant data, a KDL session may be needed to find what the system has deadlocked on.

I did a "git status" multiple times, and it worked correctly. Then I did a "git stash" and it hanged. I can launch new Terminals, move around windows, but Deskbar menu doesn't open, nor I can open any new Tracker window. Doing a "ls" in another terminal hangs as well.
Syslog doesn't show anything useful: slab memory manager: created area 0xffffffff8e801000 (9264) slab memory manager: created area 0xffffffff8f001000 (10536) slab memory manager: created area 0xffffffff8f801000 (10537) slab memory manager: created area 0xffffffff90001000 (10538) slab memory manager: created area 0xffffffff90801000 (10539) slab memory manager: created area 0xffffffff91001000 (10540) slab memory manager: created area 0xffffffff91801000 (10541) slab memory manager: created area 0xffffffff92001000 (10542) slab memory manager: created area 0xffffffff92801000 (10543) slab memory manager: created area 0xffffffff93001000 (10544) slab memory manager: created area 0xffffffff93801000 (10545) slab memory manager: created area 0xffffffff94001000 (10550) slab memory manager: created area 0xffffffff94801000 (10551) slab memory manager: created area 0xffffffff95001000 (10552)
Launching "kernel_debugger" in a terminal window hangs, as well, without entering kernel debugger. This keyboard doesn't have sysreq so I can't enter kernel debugger with ALT-SYSREQ-D.

I was able to launch two more terminals (I have three opened now), then opening one more terminal failed, and the first terminal started failing to update its window

Interestingly, this seems to happen only with haikuports repo, as now.

It actually just happened with other repos, so no.

You mean in a terminal, before git commands ? Seems not to make any difference (see attachment)

Found the problem: it's related to the "virtio" emulated storage. I changed the disk to "SATA" and the problem went away.

Sounds related to #18286. IIRC there was an older bug that mmlr fixed a while back which could also cause this.

The symptoms described in #18286 are identical to the ones I'm experiencing, so I'd say it's the same problem

Proposed change: https://review.haiku-os.org/c/haiku/+/7048
qemu with "-serial stdio" will output the serial log, if the syslog to serial output is enabled. Please provide this log.
