Re: [gentoo-user] Long boot time after kernel update

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

[gentoo-user] ssh problem
I want to login to a remote site using 'ssh'. The response I get is "Unable to negotiate with port : no matching host key type found. Their offer: ssh-rsa,ssh-dss". Yesterday, I updated 'openssh' : Installed versions: 8.8_p1-r4^t([2021-12-25 06:12:24]) (X ssl -X509 -audit -debug -hpn -kerberos -ldns -libedit -livecd -pam -pie -scp -sctp -security-key -selinux -static -test -xmss ABI_MIPS="-n32" KERNEL="linux") Occasionally, I have had a similar problem trying to do this, but ordinarily it has worked smoothly. Does anyone have helpful suggestions how to get past the blockage ? -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca
