Hi kvm-ers,
When I boot the HURD with
kvm -m 768 -net nic,model=ne2k_pci -net user hurd-installed.qemu
it hangs and eventually produces two messages:
hd0: unexpected_intr: status=0x58 { DriveReady SeekComplete DataRequest }
hd0: irq timeout: status=0x58 { DriveReady Seek Complete DataRequest }
More details below[1].
Adding -no-kvm-irqchip to the kvm command line fixes it --- no
more hangs or confusing messages (thanks, Guillem!).
Bisects (thanks to Michael for the idea) to
v2.6.37-rc1~142^2~39 (KVM: Check for pending events before
attempting injection, 2010-07-27).
Bisection log and kernel configuration available upon request (but
probably not too relevant --- the 2.6.37 distro kernel from Debian
exhibits the same problem). Reproducible with kvm/master (2d4b4d26,
2011-02-01).
CPU is a dual-core AMD Athlon II P360, family 16, model 6.
Any hints for tracking this down? For those wanting to follow along
at home, you can find a HURD cd to try at [2].
Reproduced on AMD, not on Intel. Given that I see a few PIC and PIT
PIOs before the hang, the problem is likely at the PIT. Will look further.
