After upgrade from kernel 3.7.10 to 3.10.17 (both gentoo-sources) boot time has increased from 50 seconds to 80 seconds.
The most significant delay happens at the beginning of boot, before OpenRC and all the services are started. A piece of dmesg:
| Code: | [ 1.879610] hid-generic 0003:046E:550F.0001: input: USB HID v1.10 Keyboard [BTC USB Multimedia Keyboard] on usb-0000:00:1d.7-8.4/input0
[ 1.901951] input: BTC USB Multimedia Keyboard as /devices/pci0000:00/0000:00:1d.7/usb1/1-8/1-8.4/1-8.4:1.1/input/input4
[ 1.912106] hid-generic 0003:046E:550F.0002: input: USB HID v1.10 Device [BTC USB Multimedia Keyboard] on usb-0000:00:1d.7-8.4/input1
[ 21.865252] scsi 4:0:0:0: Direct-Access TS128MJFLASHA 1.00 PQ: 0 ANSI: 2
[ 21.865703] sd 4:0:0:0: Attached scsi generic sg2 type 0
[ 21.872431] sd 4:0:0:0: [sdc] 253400 512-byte logical blocks: (129 MB/123 MiB) |
Bootchart shows that time is wasted by the three "async_port_probe" initcalls.
Also tried gentoo-sources 3.12.6, but the boot delay is still there.
Unfortunately my kernel debugging skills are not very strong, so I'm stuck at this point. What can I do about those "async_port_probe" initcalls?
Anybody had similar issues? Maybe a relevant kernel bug already exists?
Thanks in advance! |
