Hi. There is a BUG message from SLUB during boot process: -- May 21 05:39:10 midgard kernel: [ 31.177484] BUG: at include/linux/slub_def.h:77 kmalloc_index() May 21 05:39:10 midgard kernel: [ 31.178355] [<c01062ca>] show_trace_log_lvl+0x1a/0x30 May 21 05:39:10 midgard kernel: [ 31.179263] [<c0106e72>] show_trace +0x12/0x20 May 21 05:39:10 midgard kernel: [ 31.180177] [<c0106ee6>] dump_stack +0x16/0x20 May 21 05:39:10 midgard kernel: [ 31.181094] [<c018440d>] get_slab +0x1cd/0x260 May 21 05:39:10 midgard kernel: [ 31.182024] [<c0185809>] __kmalloc_track_caller+0x19/0xa0 May 21 05:39:10 midgard kernel: [ 31.183019] [<c0170059>] __kzalloc +0x19/0x50 May 21 05:39:10 midgard kernel: [ 31.184012] [<df05586e>] usb_get_configuration+0x9de/0x11c0 [usbcore] May 21 05:39:10 midgard kernel: [ 31.185115] [<df04cd07>] usb_new_device+0x17/0x190 [usbcore] May 21 05:39:10 midgard kernel: [ 31.186181] [<df04e68a>] hub_thread +0x79a/0xfd0 [usbcore] May 21 05:39:10 midgard kernel: [ 31.187185] [<c013b8e2>] kthread +0x42/0x70 May 21 05:39:10 midgard kernel: [ 31.188190] [<c0105ea7>] kernel_thread_helper+0x7/0x10 --
kzalloc(0, GFP_KERNEL) occurs in drivers/usb/core/config.c in usb_get_configuration function. I already wrote about this slub bug report and offered a patch(http://www.uwsg.iu.edu/hypermail/linux/kernel/0705.1/0154.html). I don't know, may be it is not major thing, if it is, just ignore it. I just think, that -- length = ncfg * sizeof(struct usb_host_config); dev->config = kzalloc(length, GFP_KERNEL); -- isn't clear, because ncfg - in my case - is 0 and I suppose, that size of the leastest slab cache can become(in future) smaller than sizeof(struct usb_host_config). Thanks for attention. -- Dan Kruchinin <[EMAIL PROTECTED]> ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
