error after upgrade to 4.0 from 3.4 and with fresh install

[raj]

Hi Team,

Was running 3.4 fine and followed the guide to upgrade from 3.4 to 4 and it did not go well.

So I decided to rebuild with the 4 iso cd but getting the exact errors.

Hardware is an ibm x3850 M2 with ServeRAID-MR10k SAS RAID controller with BBU.

The error is as follows

megaraid_sas 0000:04:00:0 command timeout from megasas_get_seq_num


not tainted 4.2.2-1-pve

I attach a pic for better view

Can anyone advise please?

Regards,

Raj

Are you sure HW RAID Bios is up to date, then test again.

 

[raj]

ok i updated the hw bios and still the same. What i noticed is that in 3.4 there is a different driver that loads compared to 4

the driver is :

shpchp ata_piix pata_acpi ata_generic megaraid_sas

in proxmox 4 its different and its just after that driver loads that the system crashes

Can anyone help please

regards,

Raj

This is old but try it: https://bugzilla.redhat.com/show_bug.cgi?id=541615

iommu=calgary

or

iommu=soft

Hi sigxcpu,

This is happening while install itself as to when you select to install proxmox on the box and it starts to load in ram.

The only difference I can see is that driver that loader just before.

Any ideas

So what? Type linux iommu=soft or debug iommu=soft at the installer boot prompt.

Hi,
"iommu=soft" works with our ibm x3850 M2.
After testing, I put it in /etc/default/grub..
(thanks for the hint!)

"iommu=soft" works with our ibm x3850 M2.

Hi,
After a lot of testing, I have to say, "iommu=soft" / kernel 3.19 / 4.1 / 4.2 seems to make the system very slow with high load

I switched back to kernel 3.10, which works very well with pve4 on this old hardware...
