I a running debian unstable with occasionally latest devel kernels.
Leaving out bugs created and fixed during devel cycles, I have usually
had good success - but that is mostly uniprocessor (U5, U10, V100, X1,
Blade 100, sometimes U1) and the only SMP sparc I run often is
2-CPU E3500. Sometimes also 6-CPU E3000 and 4-CPU E450.
The only persistent problem I have had with sparclinux is ALi IDE DMA
badness - hardware bugs that contain different workarounds in drivers
but these are not 100% successful. Blade 100, V100 and X1 all have ALi
IDE. With old IDE driver the machine was unusable - hard hang quickly.
With current libata pata_ali it usually works - I can run for months
with weekly package upgrades in unstable, and compiling kernels. But if
I try to copy large amount of data to the disk from network, hangs still
occur. So avoid running your disks off onboard ALi IDE if you want the
machines to be more than toys. CMD IDE and anything SCSI have been
stable. Qlogic FC is OK, Sun socal FC lacks a Linux driver, have not
used any other FC HBA with sparclinux.
There was a long-standing stability bug in SMP sparc kernels that the
buildd's experienced but that was supposedly fixed for lenny release
AFAIK... but as you experienced problems, there's certainly something
