Hi List,

my message.log shows:

 The following is only an harmless informational message.
 Unless you get a _continuous_flood_ of these messages it means
 everything is working fine. Allocations from irqs cannot be
 perfectly reliable and the kernel is designed to handle that.
 gzip: page allocation failure. order:1, mode:0x20, alloc_flags:0x30 pflags:0x402000
Pid: 15317, comm: gzip Not tainted 2.6.32.24-0.2-xen #1
 Call Trace:
 [<ffffffff80009b95>] dump_trace+0x65/0x180
 [<ffffffff803508e6>] dump_stack+0x69/0x73

Is this really harmles?

The server is xen domU
