Hello all,
I update to the last stable kernel 5.15.11-gentoo with the same
configuration as the old kernel and now, the boot time is quite long.
Test :
5.10.76-gentoo-r1 kernel : boot time 30s
5.15.11-gentoo kernel : boot time 70s
My setup (non EFI) :
- SSD 250 Go : /dev/sdd1 ext2 for boot and /dev/sdd2 ext4 for /
- SSD 250 Go /dev/sdc1 ext4 for home
- Two 2T sata disks Seagate BarraCuda 3.5 /dev/sda1 ext4 for data and
/dev/sdb1 ext4 for data backup (Not Raid)
With the new kernel, the two Seagate disks seem to make the boot time
quite longer.
Test :
booting without mounting the disks : 20s
booting with mounting only one disk : 25s
booting with both disks : more than 60s
Testing the disks :
- smartctl -s on -a /dev/sda and smartctl -s on -a /dev/sdb : No error
reported.
- fsck -a /dev/sda1 and fsck -a /dev/sdb1 : clean
- e2fsck -cfpv /dev/sda1 : clean
Nevertheless, dmesg shows a lot of errors (attached image) with the new
kernel.
Those errors do not appear with 5.10.76-gentoo-r1 kernel.
I'm rather confused...
Have you any idea ?
What does fdisk print say? Are your partitions mis-aligned?
Unlikely, but it depends how long ago they were partitioned. There's all
this stuff about switching from 512B to 4K sectors and that *could* be
the problem.
Cheers,
Wol
