Crash at network boot

[BRULE Herman]

When I boot on lan, I crash qemu:

Program received signal SIGSEGV, Segmentation fault.

Hi,

The backtrace shows it crashes in lsi_update_irq() which is in the SCSI emulation, not the
networking code. Please try and see if this happens if you use IDE or virtio-blk for your
disk drives.

Second, please provide proper information about your software stack:
- kernel version
- qemu-kvm version
- Linux distro
- hardware config

Whan I put vga card it work perfectly. I have only the bug with wmware card and particulare version of linux
- vanilla 2.6.32.22
- 0.12.5-r1
- gentoo
- core i5 750
Guest:
- gentoo kernel (based on vanilla kernel 2.6.32.16)
- VMware SVGA video driver 11.0.1
- network boot via pxe and squashfs + aufs + tmpfs

[Jes Sorensen (jes-sorensen)]

That is really odd, it sounds like memory corruption in the vmware video driver.

QEMU 0.12 is very out of date nowadays, so it's unlikely that somebody will still have a look at this ticket => I'm closing this ticket now. If you still have problems with the latest version of QEMU, please feel free to open this ticket again (or a new one).
