irc.ELF client is not working at QEMU with RTL8139? Bug reports inside

[infarmer8]

I am running the PrettyOS floppy "pretty.img" at QEMU under Ubuntu Linux with the following command:

qemu-system-i386 -L . -m 256 -fda ./pretty.img -boot a -localtime -vga vmware
-net nic,model=rtl8139 -net user -soundhw ac97 -usb -usbdevice tablet

During the launch of PrettyOS I am already getting some error messages:

Setup HID...
UHCI: Timeout! Stalled HC still active HC still active
HC still active
Transfer failed.
HID-Descriptor could not be read!
port 2: 0080h Fullspeed

> Press key to close this console. <<<

Maybe this is normal and does not matter. Then I see this:

After that, I try to launch irc.ELF . Sometimes I get this problem:

ASSERTION FAILED (current->data == data) in file 'kernel/util/ring.c', line 125
OPERATING SYSTEM HALTED!

The most far stage I have been able to advance to, was this:

It has successfully connected and I am able to see some messages printed by this server,
but I could not write any of my new messages and could not send my new messages!

This problem - is it because this irc.ELF client is at alpha development stage?
Why I am unable to write my messages? Or maybe there is some incompatibility?
Please help me to understand, is IRC client supposed to be stable or still not?

Best regards,

Hi,

thanks for your feedback!

Regarding the IRC client, it is not obvious how to use it; I just tried it out and it works as intended. To join a channel, press CTRL+j. To issue a command, press CTRL+c. To send a message to #PrettyOS (on euirc.net), press CTRL+p.

The crash from kernel/util/ring.c would require more analysis; in general it is a strong hint that something in the kernel went wrong. Unfortunately, I do not have time to do this analysis (and I would need to reproduce the issue to fix it, anyway). If you have done any analysis or even found out the reason, we would appreciate if you can tell us!
