1 Hello all,
2
3 I update to the last stable kernel 5.15.11-gentoo with the same
4 configuration as the old kernel and now, the boot time is quite long.
5
6 Test :
7 5.10.76-gentoo-r1 kernel : boot time 30s
8 5.15.11-gentoo kernel : boot time 70s
9
10 My setup (non EFI) :
11 - SSD 250 Go : /dev/sdd1 ext2 for boot and /dev/sdd2 ext4 for /
12 - SSD 250 Go /dev/sdc1 ext4 for home
13 - Two 2T sata disks Seagate BarraCuda 3.5 /dev/sda1 ext4 for data and
14 /dev/sdb1 ext4 for data backup (Not Raid)
15
16 With the new kernel, the two Seagate disks seem to make the boot time quite
17 longer.
18
19 Test :
20 booting without mounting the disks : 20s
21 booting with mounting only one disk : 25s
22 booting with both disks : more than 60s
23
24 Testing the disks :
25 - smartctl -s on -a /dev/sda and smartctl -s on -a /dev/sdb : No error
26 reported.
27 - fsck -a /dev/sda1 and fsck -a /dev/sdb1 : clean
28 - e2fsck -cfpv /dev/sda1 : clean
29
30 Nevertheless, dmesg shows a lot of errors (attached image) with the new
31 kernel.
32 Those errors do not appear with 5.10.76-gentoo-r1 kernel.
33
34 I'm rather confused...
35 Have you any idea ?
36
37 Thanks a lot for your help.

39 Regards,
