Hi! I inserted u-SD card, only to realize that it is not detected as it should be. And dmesg indeed reveals: [10994.299846] mmc0: new high speed SDHC card at address 0003 [10994.302196] kworker/2:1: page allocation failure: order:4, mode:0x16040c0(GFP_KERNEL|__GFP_COMP|__GFP_NOTRACK), nodemask=(null) [10994.302212] CPU: 2 PID: 9500 Comm: kworker/2:1 Not tainted 4.14.0-rc2 #135 [10994.302215] Hardware name: LENOVO 42872WU/42872WU, BIOS 8DET73WW (1.43 ) 10/12/2016 [10994.302222] Workqueue: events_freezable mmc_rescan [10994.302227] Call Trace: [10994.302233] dump_stack+0x4d/0x67 [10994.302239] warn_alloc+0xde/0x180 [10994.302243] __alloc_pages_nodemask+0xaa4/0xd30 [10994.302249] ? cache_alloc_refill+0xb73/0xc10 [10994.302252] cache_alloc_refill+0x101/0xc10 [10994.302258] ? mmc_init_request+0x2d/0xd0 [10994.302262] ? mmc_init_request+0x2d/0xd0 [10994.302265] __kmalloc+0xaf/0xe0 [10994.302269] mmc_init_request+0x2d/0xd0 [10994.302273] alloc_request_size+0x45/0x60 [10994.302276] ? free_request_size+0x30/0x30 [10994.302280] mempool_create_node+0xd7/0x130 [10994.302283] ? alloc_request_simple+0x20/0x20 [10994.302287] blk_init_rl+0xe8/0x110 [10994.302290] blk_init_allocated_queue+0x70/0x180 [10994.302294] mmc_init_queue+0xdd/0x370 [10994.302297] mmc_blk_alloc_req+0xf6/0x340 [10994.302301] mmc_blk_probe+0x18b/0x4e0 [10994.302305] mmc_bus_probe+0x12/0x20 [10994.302309] driver_probe_device+0x2f4/0x490 Order 4 allocations are not supposed to be reliable... Any ideas? Thanks, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
