Hm, I believe that no patches should be necessary. I've finally managed to
install 2.6.16 on my ss20 with hypersparc processor, it worked ok so far,
but I wasn't really stressing it. From experience, it is really picky
about memory layout, and a total of 448MB strikes me as slightly odd. Try
leaving something like 128MB and see whether the situation will improve.
448MB (7x 64MB) is the best you get when the VSIMM is installed to be able to
use the CG14 SX frame buffer.
There's only one memory slot you can use for the VSIMM, so there is not much
you can do wrong with memory layout.
Thanks for your answer. I have tested some configurations with a lot of
sun4m workstations (SS5 with MicroSPARC-II/85, SS20 with one or two
SuperSPARC-II/75, SS20 with one, two or four HyperSPARC/200). Memory
configuration were :
- 256 MBytes
- 448 MBytes + VSIMM
- 512 MBytes
I have tested with one, two (raid1), three (raid5) or seven
(raid1+raid5) SCSI disks. The observed mistake seems to come from the
esp adapter, not from the HyperSPARC (but quickly appears with
HyperSPARC than Super- or MicroSPARC). In /var/log/message, I can see :

I have seen these messages on a sparc64 U1 (not a U1E) with ESP
(FAS100A) and on the SS5/SS20 I use with 2.6.16.1 or 2.6.17-rc1 kernel.
No problem on a very loaded U1E (with HME ESP) and 8 disks (raid1+raid6).
I have tried to find a workaround without any result. I think that the
trouble come from the Sbus support, but I do not understand why all but
esp FAS100A sbus modules work fine.
