Network Deadlock in R1A4

[kallisti5]

I've seen this issue twice in recent images... it's pretty bad.

1) boot system off CD. 2) Deskbar is frozen. 3) Open terminal, ifconfig freezes and waits forever.

No errors in syslog. Pulkomandy said that something may be putting junk data in one of the ports.

from the syslogs, looking at a port used by Deskbar... we get a read fault...

2648	KERN: kdebug> port 333

I've rebooted and seen this issue 2 out of 3 boots.

I tried killing net_server without success (it won't die). Going to gdb ifconfig to find out what it's doing.

Now I can't reproduce it.

I did see a few CD scsi media errors recently in syslog, so I am going to blame a bad cdrom / cheap cd media.

Removing blocker status... It will return if anyone else sees the same issue. I booted the latest R1A4 image in qemu 5-6 times without any problems.

I was unable to reproduce this bug using hrevr1alpha4-44699 in vmware and qemu. I tried qemu with the default epro1000 network card as well as rtl8193. I also tried running from the ISO in qemu to see if it was a problem on read-only medium. I'll try running on real hardware tonight.

I was also unable to reproduce this bug using hrevr1alpha4-44699 on real hardware either on the live-cd or after installing on rw media. I see no reason this bug should hold up release.

This was seen by others. Though, the issue seems to exist only on single-core machines.

It happens only on the first boot of a fresh install (or everyboot of a LiveCD) when safemode is enabled. I believe it's because in that scenario,

1. net_server is not launched via the ​Bootscript
2. the freshInstallIndicator exists, which triggers the launch of the post install scripts postInstallDir=/boot/common/boot/post_install
3. lastly, default_deskbar_items.sh will unconditionally install NetworkStatus into Deskbar.

luroh was able to confirm that commenting out /boot/system/apps/NetworkStatus --deskbar from default_deskbar_items.sh allows Haiku to boot successfully into safemode on the first boot.

As far as R1a4 is concerned, this has been noted as a Known Issue in the Release Notes.

Great... my laptop now has had this problem 2 out of the last 3 boots on R1A4.

Another solution may be to burn the anyboot to an ISO, and choose the 'install' option vs the 'LiveCD' mode.

The problem (if it is really the same one) can be repeated here on my single core machines with an R1Alpha3 CD as well, if I boot in safe mode and select Live-CD. VMware can also repeat the problem if I boot a virgin vmdk in safe mode using a single core vm.

Please check if this problem persists with hrev44832 or later.

[luroh]

My home brewed gcc2 virgin vmdk hrevr1alpha-44699 can repeat the problem every time when booting in safe mode, but my hrevr1alpha-44701 can not. Both very clean builds. I think this bug has been squashed.

Thanks for verifying!
