It's an atomic order-6 allocation, the chances for this to succeed
after some uptime become infinitesimal. The chunks > order-2 are
pretty much exhausted on this dump.
64 pages, presumably 256k, for fw->boot_size while current ipw
firmware images have ~188k. I don't know jack squat about this
driver, but given the field name and the struct:
struct ipw_fw {
__le32 ver;
__le32 boot_size;
__le32 ucode_size;
__le32 fw_size;
u8 data[0];
};
fw->boot_size alone being that big sounds a bit fishy to me.
