RE: [Xen-devel] hdc: lost interrupt
I am seeing a kernel message, "hdc: lost interrupt", when
running LTP on
the xen0 domain. The first time I saw the 'kernel: hdc: lost
interrupt'
in /var/log/messages, I was running LTP on both xen0 and xenU
domains.
We've had one or two reports of interrupt related weirdness. We're
hoping (perhaps optimistically) that these might go away when the IOAPIC
configuration code gets moved out of Xen and into domain 0, getting
upgraded to 2.6 code in the process.
I'm not sure if it is xen related or not but when I put following in
/etc/exports
/ 10.0.10.5/24(ro,sync,no_root_squash)
and then procedeed to use dom0 as nfs root server, it would hung pretty
reliably with "dma timeout" errors, and require power-cycle. the fix was
to replace "sync" with "async" as shown below.
/ 10.0.10.5/24(ro,async,no_root_squash)
that was for xen 2.0.1 and 2.6.9
FWIW.
