This looks like
https://gitlab.freedesktop.org/drm/intel/-/issues/2424
still happening at
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_9090/shard-skl5/igt@gem_userptr_blits@sync-unmap-cycles.html

Could you update the filter to include sync-unmap-cycles as well?

Looks like shard-iclb3 has a file system corruption, or just broken
storage device/host:
<3>[  240.012780] blk_update_request: I/O error, dev sda, sector 76863120 op 0x1:(WRITE) flags 0x800 phys_seg 10 prio class 0

This has been consistently happening now for a while on the shard-iclb3
machine leading to the same hang, see for instance
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_9063/shard-iclb3/pstore7-1601302770_Panic_1.txt

Similar sporadic filesystem errors have been also happening on
shard-iclb4.

I haven't seen any recent I/O errors on any of the other 7 shard-icl
machines.

shard-iclb3/4 would probably need reinstall/new storage device/new host.
