Hi,

I experimented 'SIR Reset' on an Ultra1e. Before searching on Google, I
noticed that I/Os and 'SIR reset' freezes were correlated. On mail
archives, I read "your cpu" or "your mb is gone"...

*In my case*, I've all the reasons to think that it is the disk. On the
same host with another disk, no 'SIR Reset' even after dumping the FS.
On an Ultra10 with the same disk, 'SIR Reset' freezes appeared after
hundreds MB of tar... On another Ultra1, same freezes with the disks
after some big I/Os. With others disks, all these hosts are OK under the
same conditions.

The OS tested was NetBSD/sparc64 (2.0 and 2.1) but it doesn't care AFAIU.

HTH,
