And I might git-bisect that at some time, but I d= o not=20 intend to do it during my precious weekend. The chances of me bisecting= it=20 increase with workable suggestions on how to cut down the amount of ite= rations=20 needed and avoid testing highly experimental between 3.12 and 3.13-rc1 = kernels=20 on a production laptop. I may be willing to test a patch or two. As I s= ee=20 there seem to have been quite some changes in MMC subsystem. Hi! Just does that on a ThinkPad T520 with: merkaba:~> lspci -nn | grep MMC 0d:00.0 System peripheral [0880]: Ricoh Co Ltd PCIe SDXC/MMC Host Contr= oller=20 [1180:e823] (rev 08) Mouse pointer freezes, no Ctrl-Alt-F1. merkaba:~> fdisk -l /dev/mmcblk0 Disk /dev/mmcblk0: 31.4 GB, 31439454208 bytes 255 heads, 63 sectors/track, 3822 cylinders, total 61405184 sectors Units =3D sectors of 1 * 512 =3D 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/mmcblk0p1 8192 61405183 30698496 c W95 FAT32 = (LBA merkaba:/sys/block/mmcblk0#2> grep . * 2>/dev/null alignment_offset:0 capability:10 dev:179:0 discard_alignment:0 ext_range:8 force_ro:0 inflight: 0 0 range:8 removable:0 ro:0 size:61405184 stat: 176 33 1672 102 0 0 0 = 0 =20 0 102 102 uevent:MAJOR=3D179 uevent:MINOR=3D0 uevent:DEVNAME=3Dmmcblk0 uevent:DEVTYPE=3Ddisk I do not want to take the time to diagnose this further, especially as = its one=20 of those nasty "I just lock up and I don=B4t tell you what went wrong" = kind of=20 bugs. Thats just not a nice way to tell that there has been an error. If there is any five or ten minute information gathering task, I am wil= ling to=20 provide more information, but right now there is no chance on Earth tha= t I=20 will be bisecting while having a long list of more interesting things t= o do=20 than that. Thus for now I just use 3.12 kernel again. Maybe I will try with some r= c5 or=20 so again.
