This has been broken for months. On resume, we call acpi_pci_link_set() with interrupts off, so we get a warning when we try to do a kmalloc of non atomic memory. The actual allocation is just 2 long's (plus extra byte for some reason I can't fathom), so a simple conversion to GFP_ATOMIC is probably the safest way to fix this. The error looks like this.. Debug: sleeping function called from invalid context at mm/slab.c:2486 in_atomic():0, irqs_disabled():1 [<c0143f6c>] kmem_cache_alloc+0x40/0x56 [<c0206a2e>] acpi_pci_link_set+0x3f/0x17f [<c0206f96>] irqrouter_resume+0x1e/0x3c [<c0239bca>] __sysdev_resume+0x11/0x6b [<c0239e88>] sysdev_resume+0x34/0x52 [<c023de21>] device_power_up+0x5/0xa Signed-off-by: Dave Jones <davej@redhat.com> Cc: "Brown, Len" <len.brown@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> |
