Its worse. I get a hard hang (sysrq doesn't work) during boot, just when the system goes to read the partition table.
Recap: this is an older dual cpu intel box, with a vintage HTP366 (and not a newer HPT370) on the system planar. I'm testing a configration that works fine with the old ide drivers.
It looks like libata and scsi comes up. The disk is correctly recognized; i.e. its brand, model number & size are correctly reported. printk shows that it hangs in msdos_partition, trying to read the partition table. The drive light is on full-solid, again suggesting a possible irq storm.
Same behaviour for both 2.6.22-rc5-git1 and for 2.6.22-rc4-mm2
I seem to have trouble turning on scsi logging; it doesn't seem to generate any output ...
Any suggestions on how to proceed?
