I tried pre-patch-2.3.46-1 yesterday, after having
backtracked to 2.3.40 for a while.
After having the system run for about 23 hours I again
(as I did with 2.3.41-4) saw hda: lost interrupt.
As others have said:
The 'system' locked up (even pressing the Num Lock
key didn't light up the keyboard NumLock indicator)
I could still ping in, but I couldn't telnet to it.
After resetting the machine I got the
hda: lost interrupt
during fsck time
I rebooted back to 2.3.40 and the fsck went through fine,
and then booted back into 2.3.46
I must humbly state that I still haven't taken the advice
for Andre Hedrick <andre@suse.com> (The Linux ATA/IDE guy)
and moved my second drive to the other disk controller.
(He said: You need to split the Maxtor WDC pair before you corrupt
your FS!!!!)
It's still
hda: Maxtor 86480D6, ATA DISK drive
hdb: WDC AC32100H, ATA DISK drive
hdc: NEC CD-ROM DRIVE:28B, ATAPI CDROM drive
I've been using this setup for
almost a year, and have only seen these problems with 2.4.41+
I'd really like to understand:
why it is so serious to 'mix' IDE drives, and
Perhaps explain why Andre said: "since the ASIC timing modes on the
Maxtor are better than that of the WDC, and it is the faster drive,
the error is minor." and "One should never mix a UDMA Maxtor with
DMA WDC, the chatter of the timings will kill."
Is there another work around (like some boot options...)
why did this problem just start to show up with the new kernels?
